UNION The UNION query allows you to bine the result sets of 2 or more select queries. It removes duplicate rows between the various select statements.Each SQL statement within the UNION query must have the same number of fields in the result sets with similar data types.The syntax for a UNION query is:select field1, field2, field_n from tablesUNIONselect field1, field2, field_n from tables UNION ALL The UNION ALL query allows you to bine the result sets of 2 or more select queries. It returns all rows (even if the row exists in more than one of the select statements).Each SQL statement within the UNION ALL query must have the same number of fields in the result sets with similar data types.The syntax for a UNION ALL query is:select field1, field2, field_n from tablesUNION ALLselect field1, field2, field_n from tables。IBM39。 ORDER BY supplier_city。 The ORDER BY clause sorts the result set based on the columns specified. If the ASC or DESC value is omitted, the system assumed ascending order. ASC indicates ascending order. (default)DESC indicates descending order. Example 1 SELECT supplier_city FROM supplier WHERE supplier_name = 39。 Because you have listed one column in your SELECT statement that is not encapsulated in the SUM function, you must use a GROUP BY clause. The department field must, therefore, be listed in the GROUP BY section. Having The HAVING clause is used in bination with the GROUP BY clause. It can be used in a SELECT statement to filter the records that a GROUP BY returns. The syntax for the HAVING clause is: SELECT column1, column2, ... column_n, aggregate_function (expression)FROM tables WHERE predicates GROUP BY column1, column2, ... column_nHAVING condition1 ... condition_n。 GROUP BYThe GROUP BY clause can be used in a SELECT statement to collect data across multiple records and group the results by one or more columns. The syntax for the GROUP BY clause is: SELECT column1, column2, ... column_n, aggregate_function (expression)FROM tablesWHERE predicatesGROUP BY column1, column2, ... column_n。 SELECT * FROM supplier WHERE supplier_name like 39。 SELECT * FROM supplier WHERE supplier_name not like 39。 SELECT * FROM supplier WHERE supplier_name like 39。 This would return all rows where the supplier_name is neither IBM, Hewlett Packard, or Microsoft. Sometimes, it is more efficient to list the values that you do not want, as opposed to the values that you do want. Like The LIKE condition allows you to use wildcards in the where clause of an SQL statement. This allows you to perform pattern matching. The LIKE condition can be used in any valid SQL statement select, insert, update, or delete. The patterns that you can choose from are: % allows you to match any string of any length (including zero length) _ allows you to match on a single characterSELECT * FROM supplier WHERE supplier_name like
