Syntax
LOG10
LOCATE denotes the first character position of a character expression as 1. If the search fails,
LOCATE returns 0. If either character expression is NULL, LOCATE returns a NULL value.
Example In the following example, which uses two string literals as character expressions, LOCATE returns
a value of 6:
Note char_expr1 and char_expr2 can contain multi-byte characters. The start_pos argument
specifies the position of a starting character, not a byte position. The search is case sensitive.
Character comparisons use the collation table in the database.
