OQL REPLACE

1 Description

The REPLACE function replaces all occurrences of a specified string value with another string value. The function supports limited and unlimited strings. Arguments of other types are not supported.

2 Syntax

The syntax is as follows:

1

REPLACE ( expression, pattern, replacement )

expression specifies the string to be searched.

pattern specifies the pattern to search for. In the function output, all occurrences of the pattern will be replaced with the value of replacement.

replacement specifies the string to replace the pattern.

3 Database-specific limitations

The behavior of the REPLACE function relies on underlying database implementation, which may vary by database vendor. For most supported databases, default behavior of REPLACE is case-sensitive. That means that REPLACE('ABC abc', 'abc', 'xyz') results in 'ABC xyz'. In some configurations, the behavior is case-insensitive. For example, for SQL Server, case sensitivity of REPLACE depends on used collation.
