Postgres 9.4如果不存在则创建表，例如

Question

This statement is throwing syntax errors:

CREATE TABLE IF NOT EXISTS "weChat_data_abc" LIKE "weChat_data_sample"

The table weChat_data_sample exists and is empty.

I get the error:

Error : ERROR:  syntax error at or near "LIKE"

Output of SELECT VERSION():

PostgreSQL 9.4.4 on x86_64-apple-darwin14.4.0, compiled by Apple LLVM version 6.1.0 (clang-602.0.53) (based on LLVM 3.6.0svn), 64-bit

Answer 1

Aha! I found the answer. Looks like I need to wrap the LIKE clause in parenthesis.

CREATE TABLE IF NOT EXISTS "weChat_data_abc"(LIKE "weChat_data_sample")
