以下是一些常用的SQL Server 函数,可用于查询数据库中的数据:

1. SQL SELECT 语法:SELECT name, columnNumber, COUNT(column_name) from 数据库 SELECT * FROM database WHERE name IN(column_name); 2. MIN_VALUE 语法:MIN(v1.v2.v3.vn) -- V1.v2.v3.vn; 3. CURSOR FUNCTION 语法:CURSOR(name, value) 4. LIKE INCREMENT 语法:LIKE INCREMENT(name, column_name, COUNT(column_name)) 5. LIKE INCREMENT LIMIT 语法:LIKE INCREMENT(name, column_name, COUNT(column_name)) 6. CREATE DATABASE 语法:CREATE DATABASE(name); 7. RESULT SELECT 语法:RESULT(id, value) 8. SELECT INTO (*) from 表名; 9. SELECT INTO (columns) from 表名; 10. SELECT FROM (*) from 表名; 11. SELECT INTO (id) from 表名 WHERE name IN(id); 12. SELECT LIMIT INCREMENT LIMIT(name, column_name, COUNT(column_name)); 13. TRUNC LIMIT 语法:TRUNC(id, COUNT(column_name)); 14. CONVERT TO 表名; 15. INDEX TO 行; 16. INDEX NOT NULL NULL 语法:INDEX(name); 17. LOAD DATABASE 语法:LOAD DATABASE(table_name(name), table_name(column_name), COUNT(column_name)); 18. LOAD DATABASE INTEGER 语法:LOAD DATABASE(table_name(column_name), column_name(name), COUNT(column_name)); 19. LOAD DATABASE WHERE NOT DATA(INT(name='name', column='column', COUNT(column)=1)); 20. WHERE LOADING(COUNT(column)=1);

注意:这些函数的具体实现可能略有不同,可以参考其他数据库函数的文档。
