![]() In this tutorial, you have learned how to use the PostgreSQL TRANSLATE() function to substitute characters in a set with another, one-to-one, in a single operation. 'abcdefghijklmnopqrstuvxyz') Code language: JavaScript ( javascript ) You can also decrypt the message '0 o42i4p w4oo064' using the function: SELECT TRANSLATE( '0 o42i4p w4oo064', The Concat function or method has been extensively used in the database for decades to concatenate two or more words, strings, sentences, and many more. '0123456789acwrvyuiopkjhbq') Code language: JavaScript ( javascript ) The following example shows how to use the TRANSLATE() function to encrypt a message: SELECT TRANSLATE( 'a secret message', SELECT TRANSLATE( 'apple,orange,banana', ',', ' ') Code language: JavaScript ( javascript ) ![]() The following example shows how to use the TRANSLATE() function to replace comma (,) by a semi-colon ( ) in a comma-separated values list. The following illustrates the result: translate And you can easily embed a single quote in a string constant user''s log' which is how this is defined in the SQL standard. Because the string '134' has more characters than the string 'ax', the TRANSLATE() function removes the extra character in the string '134', which is '4', from the string '12345'. 'It means PostgreSQL can use only single quote for field names, table name' no, you can not use single quotes ' for column or table names.The character '1' in string '12345' is substituted by character 'a', The character '3' in the string '12345' is substituted by the character 'x'.See the following statement: SELECT TRANSLATE( '12345', '134', 'ax') Code language: JavaScript ( javascript ) Let’s see some examples of using the TRANSLATE() function to understand how it works. Since version 9.1, PostgreSQL introduced a built-in string function named CONCAT to concatenate two or more strings into one. The PostgreSQL TRANSLATE() function returns a string with the characters in the one set of characters are replaced by another set of characters. Notice that if from is longer than to, the TRANSLATE() function removes the occurrences of the extra characters in from. Is a set of characters that replaces the from in the string. Is a set of characters in the first argument ( string) that should be replaced. The PostgreSQL TRANSLATE() function accepts three arguments: You can use it to concatenate columns in PostgreSQL, concatenate string and variable, or concatenate string and int. In this article, we will look at how to concatenate strings in PostgreSQL using each of these approaches. PostgreSQL offers two ways to concatenate strings. The following illustrates the syntax of the PostgreSQL TRANSLATE() function: TRANSLATE(string, from, to) Code language: JavaScript ( javascript ) Arguments PostgreSQL allows you to easily concatenate columns, strings and int. The PostgreSQL TRANSLATE() function performs several single-character, one-to-one translation in one operation.
