Description
The LIKE() function is used to compare two character strings for matching qualities. The <expC1> specifies the matching pattern to look for. The <expC2> specifies the string in which to look. The <expC1> accepts "wildcard" characters with which to construct the pattern. Wildcard characters may represent upper case or lower case characters, but specific characters are case sensitive. The Recital/4GL supports the following wildcard characters:
| Characters | Description |
|---|---|
| ? | Matches any one character |
| % | Synonymous with ? |
| * | Matches zero or more characters |
If the LIKE() function is used in SQL mode (SET SQL ON or embedded EXEC SQL statements), the following wildcard characters are available:
| Characters | Description |
|---|---|
| _ | Matches any one character |
| % | Matches zero or more characters |
The LIKE() function returns .T. if a matching pattern is found, or .F. otherwise.
Example
?like("*Recital*", "This is Recital") .T.
