Checked, not even wrong

CodePudding user response:

The SQL database to perform the final look at what is the result

Your input is a object parameterType="com.sojson.com mon. Model. AlAccountInfo"
Use the # to obtain parameters directly in the where condition, so may not have access to the parameters, the query result is 0

Can try to enter use # (object. The property) to obtain or enter into a map parameterType="map for Java. Util."

CodePudding user response:

You navicate execution, parameters of quotes

CodePudding user response:

Because of your database is not empty fields ""
