Hi T0t0shka ,
We get this Error, because the data types are Incompatible.
Use, Proper Conversion functions TO_NUMBER,TO_CHAR,TO_DATE to their appropriate data types.
We Often get this error, if we have a Table with Data type LONG also.
CREATE TABLE LONG_TABLE ( A LONG, B VARCHAR2(10) );
When you Perform a SELECT as
SELECT *
FROM long_table
WHERE b LIKE '%sj%';
We wont get error.
SELECT *
FROM long_table
WHERE a LIKE '%sj%';
We get Inconsistent datatypes error.
Thanks,
