使用通配符

Question

Can anyone help me out with this-

There is a column in the database as "TEXT". This column hold some string value. I want to search any row that is having '%' in this column .

For eg how will i search for a row having value 'Vivek%123' in the column TEXT

Answer 1

您必须转义％字符

WHERE COL1 LIKE 'Vivek@%123' ESCAPE '@' ;

Answer 2

In sql there is something known as an escape character, basically if you use this character it will be ignored and the character right behind it will be used as a literal instead of a wildcard in the case of %

WHERE Text LIKE '%!%%'
ESCAPE '!' 

The above sql statement will allow you to search for any string containing a percentage character '%' so it could find anything in the format of

string%string
