SQL2005以后的查询主键约束SQL

select s.name as TABLE_SCHEMA, t.name as TABLE_NAME, k.name as CONSTRAINT_NAME, c.name as COLUMN_NAME, ic.key_ordinal AS ORDINAL_POSITION
from sys.key_constraints as k
join sys.tables as t on t.object_id = k.parent_object_id
join sys.schemas as s on s.schema_id = t.schema_id
join sys.index_columns as ic on ic.object_id = t.object_id and ic.index_id = k.unique_index_id
join sys.columns as c on c.object_id = t.object_id and c.column_id = ic.column_id
where k.type = ‘PK’ and s.name=’fdp_bfm’
order by 1,2,3

  1. CREATE TABLE #counts(table_name varchar(255),row_count int);
    EXEC sp_MSForEachTable @command1=’INSERT #counts (table_name, row_count) SELECT ”?”, COUNT(*) FROM ?';
    SELECT * FROM #counts order by 1;

    再发一个可以查询数据库里面，每个表数据记录条数的SQL， 估计很少人用到这个函数

To create code blocks or other preformatted text, indent by four spaces:

    This will be displayed in a monospaced font. The first four 
    spaces will be stripped off, but all other whitespace
    will be preserved.
    
    Markdown is turned off in code blocks:

To create not a block, but an inline code span, use backticks: 

Here is some inline `code`.
