Deletes the leading or trailing character, or both, from a table column. The TRIM function only deletes characters located in the specified position.
Syntax:
Trim( LEADING|TRAILING|BOTH trimmed_char FROM column_reference )
The first parameter indicates the position of the character to be deleted, and has one of the following values:
Value |
Description |
LEADING |
Deletes the character at the left end of the string. |
TRAILING |
Deletes the character at the right end of the string. |
BOTH |
Deletes the character at both ends of the string. |
The trimmed character parameter specifies the character to be deleted, if present. Case-sensitivity is applied for this parameter. To make TRIM case-insensitive, use the UPPER function.
FROM specifies the column from which to delete the character.
Example:
SELECT * FROM test WHERE Trim( BOTH " " FROM last) = 'Smith'
