hi all,

i am getting

C#

Arithmetic overflow error converting varchar to data type numeric.

this error.
the code script is below

C#

Declare @Amount Decimal(18,4)

Declare @strSql VARCHAR(MAX)

SET @strSql =''

SET @strSql = 'UPDATE TABLE1 SET col1='+@Amount+' where id=1'
print @strSql 

--EXEC(@strSql)

i am using exec because the where condition is dynamic.the table column is also has the same type.

Please help me out.

What is the current value of @Amount when your procedure throws its error?

Solution 1

Two things you need to fix:
1) Give @Amount a value - at present it is null, so it won;t work too well.
2) Convert @Amount to a VARCHAR

SQL

Declare @Amount Decimal(18,4)
Declare @strSql VARCHAR(MAX)
SET @strSql =''
SET @Amount=0.0
SET @strSql = 'UPDATE TABLE1 SET col1='+CONVERT(VARCHAR, @Amount)+' where id=1'
print @strSql
