Appends a record to the end of a table that contains the specified field values.
Syntax INSERT INTO dbf_name [(fname1 [, fname2, ...])] VALUES (eExpression1 [, eExpression2, ...]) Or ? INSERT INTO dbf_name FROM ARRAY ArrayName | FROM MEMVAR Arguments INSERT INTO dbf_name Specifies the name of the table to which the new record is appended. dbf_name can include a path and can be a name expression. If the table you specify isn抰 open, it is opened exclusively in a new work area and the new record is appended to the table. The new work area isn抰 selected; the current work area remains selected. If the table you specify is open, INSERT appends the new record to the table. If the table is open in a work area other than the current work area, it isn抰 selected after the record is appended; the current work area remains selected. [(fname1 [, fname2 [, ...]])] Specifies the names of the fields in the new record into which the values are inserted. VALUES (eExpression1 [, eExpression2 [, ...]]) Specifies the field values inserted into the new record. If you omit the field names, you must specify the field values in the order defined by the table structure. If SET NULL is ON, INSERT - SQL attempts to insert null values into any fields not specified in the VALUES clause. FROM ARRAY ArrayName Specifies the array whose data is inserted into the new record. The contents of the elements of the array, starting with the first element, are inserted into the corresponding fields of the record. The contents of the first array element are inserted into the first field of the new record; the contents of the second array element are inserted into the second field, and so on. FROM MEMVAR Specifies that the contents of variables are inserted into fields with the same names as the variables. If a variable doesn 抰 exist with the same name as the field, the field is left empty. Remarks The new record contains the data listed in the VALUES clause or contained in the specified array or variables. The record pointer is positioned on the new record. 例子 INSERT - SQL Command Examples The following example opens the employee table and adds one record. USE employee INSERT INTO employee (emp_no, fname, lname, officeno) ; VALUES (3022, "John", "Smith", 2101) The following example opens the customer table in the testdata database. The contents of the current record are scattered to variables, and the table抯 structure is copied to a new table named cust2. INSERT - SQL is used to insert a new record in the cust2 table, and BROWSE is issued to display the new record. CLOSE DATABASES CLEAR OPEN DATABASE SYS(2004) + "samples\data\testdata" USE Customer && Open customer table * Scatter current record to memory variables SCATTER MEMVAR * Copy structure of current table to example table COPY STRUCTURE TO cust2 * Insert record from memory variable INSERT INTO cust2 FROM MEMVAR SELECT CUST2 BROWSE * Close and delete example table USE DELETE FILE cust2.dbf |
