在 SQL Server 中生成数据字典可以通过以下步骤实现:
SELECT
TABLE_NAME,
COLUMN_NAME,
DATA_TYPE,
CHARACTER_MAXIMUM_LENGTH,
IS_NULLABLE,
COLUMN_DEFAULT
FROM INFORMATION_SCHEMA.COLUMNS
WHERE TABLE_NAME = 'YourTableName'
SELECT
TableName = t.name,
IndexName = ind.name,
ColumnName = col.name,
ind.type_desc,
ind.is_unique
FROM sys.indexes ind
INNER JOIN sys.index_columns ic ON ind.object_id = ic.object_id and ind.index_id = ic.index_id
INNER JOIN sys.columns col ON ic.object_id = col.object_id and ic.column_id = col.column_id
INNER JOIN sys.tables t ON ind.object_id = t.object_id
WHERE t.name = 'YourTableName'
SELECT
TableName = t.name,
ConstraintName = c.name,
ConstraintType = c.type_desc,
ColumnName = col.name
FROM sys.tables t
INNER JOIN sys.default_constraints dc ON t.object_id = dc.parent_object_id
INNER JOIN sys.columns col ON dc.parent_object_id = col.object_id AND dc.parent_column_id = col.column_id
INNER JOIN sys.check_constraints cc ON t.object_id = cc.parent_object_id
INNER JOIN sys.columns col2 ON cc.parent_object_id = col2.object_id AND cc.parent_column_id = col2.column_id
WHERE t.name = 'YourTableName'
通过以上步骤,可以在 SQL Server 中生成数据字典,帮助用户更好地了解数据库结构和设计。
