Azure SQL Database查询编辑器中To_date函数未识别错误求助

Got it, let's clear this up for you! The To_date function you're trying to use doesn't exist in the Transact-SQL (T-SQL) dialect that Azure SQL Database relies on—that's exactly why you're hitting that error.

The Core Issue #

TO_DATE() is a go-to date conversion function for databases like Oracle or PostgreSQL, but Azure SQL Database (and SQL Server) uses T-SQL, which has its own set of built-in date handling functions. T-SQL doesn't include TO_DATE, hence the 'To_date' is not a recognized built-in function name message.

Fixes for Your INSERT Statement #

You've got three straightforward T-SQL alternatives to get that date value into your table correctly:

1. Use CONVERT() (most flexible) #

CONVERT lets you explicitly define your date string's format, which is great for avoiding ambiguity:

INSERT INTO Table_name (column1, column2, column3, column4)
VALUES ('TRP040', 'Ford Magnum', 27070, CONVERT(DATE, '12/03/2014', 103));

The 103 parameter here tells T-SQL to interpret the string as dd/mm/yyyy—perfect for your input.

2. Use CAST() (simpler, for unambiguous formats) #

If your date string uses a format T-SQL can reliably parse (like dd/mm/yyyy here), CAST works as a concise option:

INSERT INTO Table_name (column1, column2, column3, column4)
VALUES ('TRP040', 'Ford Magnum', 27070, CAST('12/03/2014' AS DATE));

3. Use PARSE() (more readable, for culture-specific formats) #

If you want syntax that makes the format obvious at a glance, PARSE lets you specify the culture corresponding to your date format:

INSERT INTO Table_name (column1, column2, column3, column4)
VALUES ('TRP040', 'Ford Magnum', 27070, PARSE('12/03/2014' AS DATE USING 'en-GB'));

en-GB uses the dd/mm/yyyy format, so this matches your input perfectly.

Quick Heads-Up #

Double-check that your date string aligns with the format you're specifying. For example, if you accidentally used 101 (which is mm/dd/yyyy) with your 12/03/2014 string, it would parse as December 3rd instead of March 12th—easy mistake to avoid!
