com.microsoft.sqlserver.jdbc.sqlserverexception：参数编号1无效

Question

Using JDBC SQL driver, I receive the following error:

com.microsoft.sqlserver.jdbc.sqlserverexception: the parameter number 1 is not valid.

The relevant code is as follows:

CallableStatement preparedCall;
String sql = "{call [dbo].[my_sproc] (?) }";
preparedCall = conn.prepareCall(sql, ResultSet.TYPE_FORWARD_ONLY, ResultSet.CONCUR_READ_ONLY);

DBLookup.setObject(preparedCall, 1, "Some value");

ParameterMetaData pmd = ps.getParameterMetaData();
int parameterType = pmd.getParameterType(1); //<-- here is where it's thrown

Answer 1

This can be caused by the connecting user credentials not having appropriate access to the stored procedure in SQL Server.

Grant EXECUTE permissions and this should be resolved.
