There is a table with the following columns: text1, type longtext text2, type longtext
There is a third-party reporting system that receives the request and wraps it up, for example, sent the request:
SELECT text1, text2 FROM test
He converts it to this form:
SELECT CAST(`text1` as VARCHAR(100)) as text1, CAST(`text2` as VARCHAR(100)) as text2 FROM ( SELECT text1, text2 FROM test ) t
Accordingly, now mysql swears that CAST cannot be used like this:
MySQL][ODBC 3.51 Driver][mysqld-5.5.50-0+deb8u1]You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'VARCHAR(100)) AS text1, CAST(`text2` AS VARCHAR(100)) AS text2 at line 1
Actually the question is, how can you change the initial request so that the system request executes without errors?
