How to build dynamic query strings in the query using DB adapter 'Pure SQL'
Satya SApr 16 2012 — edited Feb 26 2020Dear Forum,
I am building an application which will access DB to fetch some result set. The query involves retrieving data from multiple tables(nearly 10 tables). So I have created a DB adapter using 'execute pure sql' option. With this query works fine, but my inputs parameters will vary. So I need to make my query dynamic to append the query strings at runtime depending on the inputs.
For example I have 3 input variables - input1,input2 and input3 (in my request xsd) which are used in the pure sql query. Now if I get a 4th input parameter input4 in the request, I need to append this to query string as 'AND input4=[some value]' at runtime. Otherwise my query should have only 3 parameters. Please suggest how this can be achieved.
Regards,
Satya.
