I have a column toysid
which is of varchar
datatype in one table. Also another table having same the column toysid
with int
datatype (I know I can modify column for first table but I have to follow some procedure to keep it as varchar
).
I have written following query to join the table:
select study.toysid from study join concepts on study.toysid = concepts.toysid
The query returns error:
Conversion failed wher converting varchar datatype into int
Hence I have tried below query:
select study.toysid from study join concepts on convert(int, study.toysid) = concepts.toysid
I got the same error. How to convert it? I have searched in many websites but I’m unable to get solution. Please anyone help on this.
