PreparedStatementCallback: Parameter Index Out of Range Error - Java SQL Exception

PreparedStatementCallback; SQL [select id,un_code from t_dept where un_code in ('values')]; Parameter index out of range (1 > number of parameters, which is 0).; nested exception is java.sql.SQLException: Parameter index out of range (1 > number of parameters, which is 0)

This error typically arises due to a mismatch in the number of parameters. In your SQL query, you're using a parameter placeholder ('values'), but no corresponding parameter value is supplied.

To rectify this, examine your code and ensure that you're setting parameter values correctly before executing the SQL query. Utilize the 'setXXX' methods of the PreparedStatement object to assign values to parameters, where 'XXX' denotes the parameter's data type. For instance, if 'un_code' is a string parameter, employ the 'setString' method to set its value.

Additionally, confirm that the count of parameter values aligns with the number of parameter placeholders in your SQL statement. In this instance, your SQL query has a single parameter placeholder ('values'), hence the provided parameter value count should also be one.
