下面的SQL脚本在我的结束完美地工作。

SELECT column_name AS 'Column Name',data_type AS 'Data Type' 
FROM information_schema.columns 
WHERE table_name = '[Table Name]'

使用SQL Server:

SELECT DATA_TYPE 
FROM INFORMATION_SCHEMA.COLUMNS
WHERE 
     TABLE_SCHEMA = 'yourSchemaName' AND
     TABLE_NAME   = 'yourTableName' AND 
     COLUMN_NAME  = 'yourColumnName'

下面的SQL脚本在我的结束完美地工作。

SELECT column_name AS 'Column Name',data_type AS 'Data Type' 
FROM information_schema.columns 
WHERE table_name = '[Table Name]'

如果你正在使用MySQL，你可以试试

SHOW COLUMNS FROM `tbl_name`;

在dev.mysql.com上显示列

否则你应该能做到

DESCRIBE `tbl_name`;

对于SQL Server，这个系统存储过程将返回所有表信息，包括列数据类型:

exec sp_help YOURTABLENAME

使用这个查询

SELECT * FROM INFORMATION_SCHEMA.COLUMNS
WHERE TABLE_NAME = 'TABLE_NAME'
ORDER BY ORDINAL_POSITION
