I have the code that executes some stored procedure. mssql-jdbc
driver to connect to Microsoft SQL Server database is used.
Here is simplified code
SimpleJdbcCall call = simpleJdbcCallFactory.create(jdbcTemplate)
.withSchemaName(SCHEMA)
.withProcedureName(SP)
.declareParameters(
new SqlParameter("Id1", Types.INTEGER),
new SqlParameter("Id2", Types.TINYINT),
new SqlParameter("Id3", Types.INTEGER))
.returningResultSet("result", (rs, rowNum) -> MappingObject.builder()
.id(rs.getInt("Id"))
.date(rs.getTimestamp("Date"))
// .......
.build());
MapSqlParameterSource params = new MapSqlParameterSource();
params.addValue("Id1", 1);
params.addValue("Id2", 2);
params.addValue("Id3", 3);
Map queryRes = call.execute(params);
When I run this I see in profiler 3 calls:
exec sp_executesql N'EXEC sp_stored_procedures @P0, @P1, @P2 ',N'@P0 nvarchar(4000),@P1 nvarchar(4000),@P2 nvarchar(4000)',N'MY_SP_NAME',N'MY_NAMESPACE',NULL
It seems that it checks that stored procedure existsexec sp_executesql N'EXEC sp_sproc_columns_100 @P0, @P1, @P2,@P3,@P4 ',N'@P0 nvarchar(4000),@P1 nvarchar(4000),@P2 nvarchar(4000),@P3 nvarchar(4000),@P4 nvarchar(4000)',N'MY_SP_NAME,N'MY_NAMESPACE',NULL,NULL,N'3'
it gets a column information of this spexec sp_executesql N'EXEC MY_NAMESPACE.MY_SP_NAME @P0, @P1, @P2 ',N'@P0 int,@P1 tinyint,@P2 int',1,2,3
and finally it executes my stored procedureI see in profiler 3 sql calls every time I run this one stored procedure. I'd like to make only one call, is it possible with SimpleJdbcCall
?
I've just found an answer, maybe this will be useful to somebody. All we need to avoid 3 calls is withoutProcedureColumnMetaDataAccess()
for SimpleJdbcCall
.
Like this
SimpleJdbcCall getQACall = simpleJdbcCallFactory.create(jdbcTemplate)
.withSchemaName(SCHEMA_ARTICLE)
.withProcedureName(SP_GET_ALL_QUESTIONS_ANSWERS)
.withoutProcedureColumnMetaDataAccess()
.declareParameters(
// etc
