String Functions and Operators 8. All of the regular expression functions use the Java pattern syntax, with a few notable exceptions:.
Returns the substring s matched by the regular expression pattern in string :. Finds all occurrences of the regular expression pattern in string and returns the capturing group number group :. Returns the first substring matched by the regular expression pattern in string :.
Finds the first occurrence of the regular expression pattern in string and returns the capturing group number group :. Evaluates the regular expression pattern and determines if it is contained within string.
This function is similar to the LIKE operator, except that the pattern only needs to be contained within stringrather than needing to match all of string. In other words, this performs a contains operation rather than a match operation. Removes every instance of the substring matched by the regular expression pattern from string :.
Replaces every instance of the substring matched by the regular expression pattern in string with replacement. Replaces every instance of the substring matched by the regular expression pattern in string using function. The lambda expression function is invoked for each match with the capturing groups passed as an array. Capturing group numbers start at one; there is no group for the entire match if you need this, surround the entire expression with parenthesis. Splits string using the regular expression pattern and returns an array.
Trailing empty strings are preserved:. Presto 0. Regular Expression Functions. Regular Expression Functions All of the regular expression functions use the Java pattern syntax, with a few notable exceptions: When using multi-line mode enabled via the? Additionally, the? Case-insensitive matching enabled via the? However, context-sensitive and local-sensitive matching is not supported.
Surrogate pairs are not supported.PRESTO strings combine more than seven decades of string making experience with latest production technologies. Only the best raw materials are used for manufacturing. Made with latest technologies and of the finest materials. Presto Nylonwound strings for double bass were designed to combine the unique sound of natural gut strings with the convinient properties of steel rope core strings. Unlike gut strings, Presto Nylonwound-strings strings stay in tune under temperature and humidity changes.
They also have a short break-in time. Presto Nylonwound-strings have a dark and mellow, but big tone with a strong sustain. They are of comparable low tension.
8.10. Regular Expression Functions
Presto Nylonwound-strings have a core of braided steel rope, wrapped with silk and metal wires. Finally, they are wound in a white-translucent polyamid monofil, and polished to a flat, smooth surface. Compared to other steel strings, Presto Nylonwound-strings are of very low tension. They are very easy to play. The thicker gauges and the smooth polyamid-surface lead to a very pleasant playing feel under your fingers.
Presto Nylonwound-strings are ideally suited for pizzicato and slapping techniques. For bowing, we recommend to roughen the bowing area with fine sandpaper, and to apply rosin directly on the strings. If strings of thinner gauges were used before, some setup work may be necessary at the saddle and bridge string notches.
Due to their steel rope core, Presto Nylonwound-strings also work well with magnetic pickups. Presto Jazzicato strings are a further development of our popular Presto Nylonwound string. They have a improved steel rope core and a black Nylon wrapping. Compared to our original Presto Nylonwound strings, the Jazzicato strings have a slightly smaller diameter. But they still have this smooth surface feel, which makes them different to other steel strings.
This particular surface feel and the low tension make the Jazzicato strings very easy to play. The powerful, dark sound, the percussive punch and the unobtrusive sustain give the Jazzicato string their very own character — ideal for Jazz pizzicato, but also suited for Slap bass and Bluegrass. By using Tungsten wire for the wrapping, we were able to give them more tension and sustain than our original Nylonwound strings, but a smaller diameter.
They break in quickly and achieve a stable tuning within a very short time. The Balance Orchestra strings are optimized for arco technique. They have dark, powerful sound, and are very easy to bow. The Balance Hybrid strings are optimized for both arco and pizzicato techniques. Played pizzicato, they have a voluminous sound and long sustain.
Nevertheless, they are easy to bow. Presto Balance Fractional are designed for fractional sized double basses. They have a low tension and small diameters, so they are easy to play even for children. They have a steel rope core, wrapped with tungsten and chromesteel. Prestoflex strings are our new versatile steel string. Our design goal was to give them a warm, powerful but even tone in all registers, and a well balanced pizzicato sustain.
They also have a very good bow response, so Prestoflex are perfectly suited for both Jazz and Orchestra. Prestoflex are made with a sleek polished chromesteel wrapping on a flexible steel rope core. They sound so bright and loud and clear and feel so smooth. They are a total joy to play and I will recommend them to all my bass playing friends!The operator performs concatenation.
These functions assume that the input strings contain valid UTF-8 encoded Unicode code points. Additionally, the functions operate on Unicode code points and not user visible characters or grapheme clusters. Some languages combine multiple code points into a single user-perceived characterthe basic unit of a writing system for a language, but the functions will treat each code point as a separate unit.
The lower and upper functions do not perform locale-sensitive, context-sensitive, or one-to-many mappings required for some languages. Specifically, this will return incorrect results for Lithuanian, Turkish and Azeri. Returns the Unicode code point n as a single character string. Returns the Unicode code point of the only character of string. Returns the concatenation of string1string2This function provides the same functionality as the SQL-standard concatenation operator.
See format. Returns the Hamming distance of string1 and string2i. Note that the two strings must have the same length. Returns the length of string in characters. Returns the Levenshtein edit distance of string1 and string2i.
Converts string to lowercase. Left pads string to size characters with padstring. If size is less than the length of stringthe result is truncated to size characters. Removes leading whitespace from string. Tests whether a string of digits is valid according to the Luhn algorithm. Returns the starting position of the first instance of substring in string. Positions start with 1. If not found, 0 is returned.
See also strpos. Removes all instances of search from string. Replaces all instances of search with replace in string.
Returns string with the characters in reverse order. Right pads string to size characters with padstring. Removes trailing whitespace from string. Splits string on delimiter and returns an array. Splits string on delimiter and returns an array of size at most limit. The last element in the array always contain everything left in the string.
Splits string on delimiter and returns the field index. Field indexes start with 1. If the index is larger than than the number of fields, then null is returned.
Splits string by entryDelimiter and keyValueDelimiter and returns a map. Splits string by entryDelimiter and keyValueDelimiter and returns a map containing an array of values for each unique key. The values for each key will be in the same order as they appeared in string. Returns the position of the N-th instance of substring in string.For example, Presto will produce an error if you ask it if John is between 2.
Both operators work for all data types. These functions are not in the SQL standard, but are a common extension. Like most other functions in Presto, they return null if any argument is null. Note that in some other databases, such as PostgreSQL, they only return null if all arguments are null.
Evaluates to true when A is equal to all values. Evaluates to true when A is smaller than the smallest value. Evaluates to true when A is equal to any of the values. This form is equivalent to A IN Evaluates to true when A is smaller than the biggest value. The LIKE operator can be used to compare values with a pattern:. An example is a query to find all continents starting with Ewhich returns Europe :. You can negate the result by adding NOTand get all other continents, all not starting with E :.
The following query uses two underscores and produces only Asia as result:. The above query returns true since the escaped underscore symbol matches. If you need to match the used escape character as well, you can escape it. If you want to match for the chosen escape character, you simply escape itself.

I still prefer Dewalt over Milwaukee any day. Milwaukee, however makes better corded products. A reader emailed in, asking about the possibility of Dewalt coming out with 20V Max brushless versions of their premium drill and hammer drill. Reply For me, DeWalt dropped the ball in the transition from their 18V stem-pack line to their 20V Max slide-pack line.
Reply Dewalt should have pushed the changer over from stem-pack to slide packs sooner it should have been 2-3 years before the actual 20v line release. Reply I think it might be awhile before we see an update on the premium drill. Reply I know brushless has turned a lot of these tools into real good tools, but some of these premium cordless tools are expensive compared to the cheaper more powerful corded counterpartsAnd like you said in this economy, money is everything.
A cordless can do great things but if your doing regular work with these tools a Corded wins everything But if you need to switch go got it but the majority of the market is going to stick with what works for themReply The 4.
The compact drills are still only kitted with 1. Reply Well all the big drill kits with the 3. Reply I believe dewalt is fairly new to the brushless technology so has not yet found the balance between brushless and high torque to come out with a brushless premium drill just yet. Size does matter, but small brushless motors are typically purposefully small. Reply One more thingif you look at the festool c12, you can see that the brushless motor is a hybrid of a common brushless motor. Reply Just ordered myself a 985 bare tool on ebay for 100 bucks Needed a big drill to do some bigger jobs around the house.
