Comparing Strings
To find out whether the value of a column matches a pattern, use:
SELECT ... WHERE <s> [NOT ] LIKE <f> [ESCAPE <h>] ...
The condition is true if the value of the column <s> matches [does not match] the pattern in the data object <f>. You can only use this test for text fields. The data type of the column must be alphanumeric. <f> must have data type C.
You can use the following wildcard characters in <f>:
% for a sequence of any characters (including spaces).
_ for a single character.
For example, ABC_EFG% matches the strings ABCxEFGxyz and ABCxEFG, but not ABCEFGxyz. If you want to use the two wildcard characters explicitly in the comparison, use the ESCAPE option. ESCAPE <h> specifies an escape symbol <h>. If preceded by <h>, the wildcards and the escape symbol itself lose their usual function within the pattern <f>. The use of _ and % corresponds to Standard SQL usage. Logical expressions elsewhere in ABAP use other wildcard characters (+ and *).
You cannot use LIKE in the ON condition of the FROM clause.
