查找数据库中的未知表中的特定列？(Find a specific column in an unkn

我试图找到一个特定的列，它是在125个表的数据库未知。 我要寻找一个通配符，说：“守望％％”。 这可能吗？

Answer 1:

SELECT TABLE_NAME, COLUMN_NAME, DATA_TYPE, IS_NULLABLE, COLUMN_DEFAULT
  FROM INFORMATION_SCHEMA.COLUMNS
 WHERE column_name LIKE '%watcher%'
[AND table_schema = 'database']

Answer 2:

这说明你有点详细信息...

DECLARE @columnName as varchar(100)
SET @columnName = 'ColumnName'

SELECT t.name AS Table, c.name AS Column,
ty.name AS Type, c.max_length AS Length, c.precision AS Precision
FROM sys.tables AS t
INNER JOIN sys.columns c ON t.OBJECT_ID = c.OBJECT_ID
INNER JOIN sys.types ty ON c.system_type_id = ty.system_type_id
WHERE c.name LIKE @columnName
ORDER BY t.name, c.name

希望能帮助到你！
