2.32 @STRFIND
Use the @STRFIND
function to determine the position of a string within a string column or else return zero if the string is not found. Optionally, @STRFIND
can accept a starting position within the string.
For this function, Oracle GoldenGate supports the use of an escape sequence to represent characters in a string column in Unicode or in the native character encoding of the Microsoft Windows, UNIX, and Linux operating systems. The target column must be a SQL Unicode data type if any argument is supplied as Unicode.
This function does not support NCHAR
or NVARCHAR
data types.
