Many trim functions have an optional parameter to specify a list of characters to trim, instead of the default whitespace characters. For example, PHP and Python allow this optional parameter, while Pascal and Java do not. With Common Lisp's string-trim function, the parameter (called character-bag) is required. The C++ Boost library defines ...
Base 1: the first character is numbered 1, and so on. Any leading or trailing whitespace is removed from the string before searching. If the requested position is negative, this function will search the string counting from the last character. In other words, number = -1 is the same as asking for the last character of the string.
This template removes the last word of the first parameter, i.e. the last non-space token after the last space. Use |1= for the first parameter if the string may contain an equals sign (=). By default, words are delimited by spaces, but the optional parameter |sep= can set the separator to any character.
find_character(string,char) returns integer Description Returns the position of the start of the first occurrence of the character char in string. If the character is not found most of these routines return an invalid index value – -1 where indexes are 0-based, 0 where they are 1-based – or some value to be interpreted as Boolean FALSE.
String interpolation, like string concatenation, may lead to security problems. If user input data is improperly escaped or filtered, the system will be exposed to SQL injection, script injection, XML external entity (XXE) injection, and cross-site scripting (XSS) attacks. [4] An SQL injection example: query = "SELECT x, y, z FROM Table WHERE ...
The purpose of a PL/SQL function is generally used to compute and return a single value. This returned value may be a single scalar value (such as a number, date or character string) or a single collection (such as a nested table or array). User-defined functions supplement the built-in functions provided by Oracle Corporation. [6]
Comma-separated values (CSV) is a text file format that uses commas to separate values, and newlines to separate records. A CSV file stores tabular data (numbers and text) in plain text, where each line of the file typically represents one data record.
To start a new table row, type a vertical bar and a hyphen on its own line: "|-". The codes for the cells in that row start on the next line. An id for § anchoring in-links, and § row style may be included on the same line. {| |+ The table's caption |-row code goes here |-next row code goes here |}
