是否可以在PostgreSQL中创建一个带有变量名的表？

Question

Using PL/pgSQL or (some other mechanism), is it possible to create a table with a variable name?

I would like to create multiple tables named table_1, table_2, table_3, etc... and it would be simpler if I could use a loop to create them, instead of explicitly creating each one.

I suspect the answer to this is no, but I would like to confirm it.

Answer 1

While I would question your design if you're relying on such tricks, your question is general and you didn't give specific information to judge either way.

It should be possible, actually. It's only a matter of programmatically building the table names as strings and then, in a loop, execute your CREATE statements as dynamic queries.

See this page in the postgres documentation: http://www.postgresql.org/docs/current/interactive/plpgsql-statements.html#PLPGSQL-STATEMENTS-EXECUTING-DYN

Answer 2

通过在循环中动态构建命令来生成脚本，然后运行生成的输出脚本。
