从 SQL 服务器执行 Oracle 11g function 并将结果插入 Z97785240A0100CB0376

Question

I have a SSIS package that query data from SQL table (using SQL Task tool) and pass it's output to a ForEach loop container that will insert value into query variable. Within the container is another SQL Task with Oracle connection to execute function in Oracle with the query. Although the package runs very slow, it still produces result. However, I need help on putting the result into a SQL table.

Furthermore, let me know if there are better ways of optimizing the package.

Thank you in advance.

Answer 1

My advice is to change the query inside the SSIS package in order to insert 1000 by 1000 instead of 1 by 1. You can play with the numbers taking in consideration the result of the performance.

INSERT ALL
  INTO mytable (column1, column2, column_n) VALUES (expr1, expr2, expr_n)
  INTO mytable (column1, column2, column_n) VALUES (expr1, expr2, expr_n)
  INTO mytable (column1, column2, column_n) VALUES (expr1, expr2, expr_n)
  ...
SELECT * FROM dual
