Exec 存储过程不适用于 JdbcCursorItemReader

Question

I need to read data from both select and exec Sybase queries using JdbcCursorItemReader in Spring-Batch. While SELECT queries run perfectly, the Exec queries are running into the following error:

Caused by: org.springframework.jdbc.UncategorizedSQLException: Executing query; uncategorized SQLException for SQL [exec proc_1]; SQL state [ZZZZZ]; error code [7773]; Execute cursor 'jconnect_implicit_1' is declared on a procedure which contains a non-SELECT or a SELECT with a COMPUTE clause. For the declaration of this cursor to be legal it should have a single SELECT statement without a COMPUTE clause.

; nested exception is com.sybase.jdbc4.jdbc.SybSQLException: Execute cursor 'jconnect_implicit_1' is declared on a procedure which contains a non-SELECT or a SELECT with a COMPUTE clause. For the declaration of this cursor to be legal it should have a single SELECT statement without a COMPUTE clause. ... 43 common frames omitted

... 45 common frames omitted

The code for the JdbcCursorItemReader is as follows:

JdbcCursorItemReader itemReader = new JdbcCursorItemReader();
ColumnMapRowMapper rowMapper = new ColumnMapRowMapper();
itemReader.setDataSource(getDataSource());
itemReader.setRowMapper(rowMapper);
itemReader.setFetchSize(batchSize);
itemReader.setSql(dataSql); //datasql is passed Sybase query

Even after using StoredProcedureItemReader as suggested, getting the following error:

Caused by: org.springframework.jdbc.UncategorizedSQLException: Executing stored procedure; uncategorized SQLException for SQL [{call ftsps_report(?, ?)}]; SQL state [ZZZZZ]; error code [7773]; Execute cursor 'jconnect_implicit_1' is declared on a procedure which contains a non-SELECT or a SELECT with a COMPUTE clause.

Have defined the StoredProcedureItemReader as follows:

StoredProcedureItemReader itemReader = new StoredProcedureItemReader();
ColumnMapRowMapper rowMapper = new ColumnMapRowMapper();
itemReader.setDataSource(getDataSource());
itemReader.setRowMapper(rowMapper);
itemReader.setFetchSize(batchSize);
itemReader.setProcedureName(dataSql);
SqlParameter[] parameter = {new SqlParameter("date1", Types.DATE),new SqlParameter("date2", Types.DATE)};
itemReader.setParameters(parameter);
itemReader.setPreparedStatementSetter(psSetter);

where psSetter setValues I have defined as follows:

ps.setDate(1, Date.ValueOf(paramList.get(0));
ps.setDate(2, Date.ValueOf(paramList.get(1));

I tried for few other stored procedures also and got similar issues. Is it an error with the definition. I just want to define parameters by index preferably. Is there any straightforward way of doing so? Is it expecing the parameters in the storedproc to be named date1/date2 specifically and failing because of that?

Answer 1

For stored procedures, you need to use the StoredProcedureItemReader and not the JdbcCursorItemReader , something like:

@Bean
public StoredProcedureItemReader storedProcedureItemReader() {
    StoredProcedureItemReader reader = new StoredProcedureItemReader();
    reader.setProcedureName("yourProcedureName");
    // set other properties
    return reader;
}

Please refer to the reference documentation for more details.
