The REGEXP_MATCHES function is used to perform regular expression pattern matching on a given string. It returns all substrings in the input string that match a specified regular expression pattern. This function is useful when you need to extract specific pieces of information from a text based on a pattern. The syntax of the REGEXP_MATCHES…

The REGEXP_REPLACE function is used to replace substrings within a string based on a regular expression pattern. It allows you to perform advanced pattern-based replacements on text data. The syntax of the REGEXP_REPLACE function is as follows: REGEXP_REPLACE(string, pattern, replacement, flags) where string is the input string in which you want to perform replacements. and…

The MD5 function is used to calculate the MD5 hash value of a given input string. MD5 (Message Digest Algorithm 5) is a widely used cryptographic hash function that produces a fixed-size 128-bit (16-byte) hash value, typically represented as a 32-character hexadecimal number. The syntax of the MD5 function is as follows: MD5(string) where string…

The ASCII function is used to return the ASCII code value of the first character in a given string. The ASCII code is a numerical representation of a character in the ASCII character set. The syntax of the ASCII function is as follows: ASCII(string) and string is the input string for which you want to…

The CHR function is used to return the character corresponding to a specified ASCII code or Unicode code point. It’s a convenient way to generate characters based on their numeric representations. The syntax of the CHR function is as follows: CHR(code) where code is the numeric code that represents the character you want to retrieve….

The LPAD function is used to pad a string on the left side with a specified character or a repeated sequence of characters, until the resulting string reaches a specified length. This function is often used to align strings to a specific width. The syntax of the LPAD function is as follows: LPAD(string, length, fill_character)…

The FORMAT function is used to format a string using placeholders that are replaced with corresponding values. It’s a powerful function that allows you to create formatted strings with specific patterns and insert values into those patterns. The syntax of the FORMAT function is as follows: FORMAT(format_string, value1, value2, …) where format_string is the string…

The SPLIT_PART function is used to extract a specific part of a string that is divided into segments by a delimiter. This function is particularly useful when you have a string that contains multiple segments separated by a delimiter, and you want to extract a specific segment based on its position. The syntax of the…

The TRANSLATE function is used to replace all occurrences of a set of characters in a given string with corresponding characters from another set. This function is particularly useful for performing character-level substitutions or transformations. The syntax of the TRANSLATE function is as follows: TRANSLATE(string, from_set, to_set) where string is the input string in which…

The SUBSTRING function is used to extract a substring from a given string. It allows you to extract a portion of a string based on a specified starting position and length. The syntax of the SUBSTRING function is as follows: SUBSTRING(string FROM start_position [FOR length]) where string is the input string from which you want…
