                    Copy

Property Value

Type	Description
String	A string that represents a filtering expression applied when data is retrieved.

Remarks

Expressions for the filter can be one of the following forms:

column = value
column > value
column >= value
column < value
column <= value
value = column
value >= column
value < column
value <= column
column IN (value)
column IN(value-list)
column NOT IN(value)
column NOT IN(value-list)
column LIKE value
expression COLLATE NOCASE
expression COLLATE RTRIM
expression COLLATE LOCALIZED
expression1 AND expression2 OR expression3 ...
Note that if you want to set quotation (" ' " or " " ") as value of LIKE operator, you should use two times. (" '' " or " "" "). And the optional ESCAPE clause is supported. Both percent symbol("%") and underscore symbol("_") are used in the LIKE pattern. If these characters are used as values of the LIKE operation, then the expression following the ESCAPE clause of sqlite will be ignored.

For example, column LIKE ('#%') ESCAPE ('#') - "#" is an escape character, it will be ignored.
