Hi,I have two columns in the same table
One is data_value (varchar) and the other is sql_data_type (varchar). Data_value holds info like dates, decimals, etc..
sql_data_type holds info about what type of data should be stored in data_value. How can i write a code so that specific_data_type goes into data_value as mentioned in sql_data_type???
Thank you

As others have said, this is a nasty kludge that needs reworking, but I applaud your desire to at least constrain the values to being valid 😀
This may point you in the right direction...
create table table1
(
data_value varchar (50) ,
sql_data_type varchar (50),
check (
case sql_data_type
when 'DATE' then cast(TRY_PARSE(data_value as date) as sql_variant)
when 'decimal' then cast(try_parse(data_value as decimal) as sql_variant)
else data_value
end is not null
),
check (
TYPE_ID(sql_data_type) is not null
)
)
