This constraint enforces column values to be unique and not null.ĭROP TABLE SQLUser. In this example, you create a new table (SQLUser.CaveDwellers), use INSERT to populate the table with data, and then use INSERT OR UPDATE to add additional rows and update existing rows.Ĭreate a table with a column, Num, that is designated as the primary key. Examples Insert or Update Rows in a Table %PROFILE_ALL collects SQLStats for the main query module and all of its subquery modulesįor more details on these keywords, see the keyword argument of the INSERT command. %PROFILE collects SQLStats for the main query module %PROFILE, %PROFILE_ALL - Generate performance analysis statistics (SQLStats) for the INSERT OR UPDATE statement. %NOTRIGGER - Do not pull base table insert triggers during INSERT OR UPDATE processing. %NOLOCK - Disable locking of the row upon INSERT OR UPDATE. %NOJOURN - Suppress journaling and turns off transactions for the duration of the insert operation. %NOINDEX - Disable setting of index maps during INSERT OR UPDATE processing. %NOFPLAN - Ignore any frozen plans for this operation and generate a new query plan. Disables the update operation of INSERT OR UPDATE. %NOCHECK - Disable unique value checking and foreign key referential integrity checking. Separate multiple keyword options by spaces. You can specify keyword options in any order. Keyword options that configure INSERT OR UPDATE processing. If the corresponding columns do not pass data type and length validation checks, InterSystems SQL generates an SQLCODE -104 error.Īn INSERT OR UPDATE with SELECT operation sets the %ROWCOUNT variable to the number of rows inserted or updated (either 0 or a positive integer). Corresponding columns can have different column names and column lengths, so long as the inserted data can fit in the table column. The SELECT query extracts column data from one or more tables and the INSERT OR UPDATE command creates corresponding new rows in its table containing this column data. queryĪ SELECT query, the result set of which supplies the data values for the corresponding columns specified in column. Thus :myupdates(), :myupdates(5,), and :myupdates(1,1,) are all valid specifications. The lowest subscript level of the array must be unspecified. arrayĪ dynamic local array of values specified as a host variable. For more details, see the value argument of the INSERT command. INSERT OR UPDATE has the same value restrictions as INSERT. Specifying more values than columns generates an SQLCODE -116 error. Specifying fewer values than columns generates an SQLCODE -62 error. valueĪ scalar expression, or comma-separated list of scalar expressions, specified in the VALUES clause that supplies the data values for the corresponding columns in column. For more details on this restriction, see IDKEY Column Values. IDKEY column values can be inserted but not updated. If omitted, the list of values is applied to all columns in column-number order. columnĪ column name or comma-separated list of column names that correspond in sequence to the supplied list of values. The name of the table or view on which to perform the insert operation. If the RecordID column enforces a UNIQUE constraint and the RecordID being inserted already exists, then INSERT OR UPDATE updates the existing row instead.īecause the %NOCHECK keyword disables unique value checking, INSERT OR UPDATE %NOCHECK always results in an insert operation and is therefore equivalent to INSERT. This statement first tries inserting a new row of data into the Sample.Records table. The insert or update of a single row sets the %ROWCOUNT variable to 1 and the %ROWID variable to the inserted or updated row. The values in the VALUES clause must correspond positionally with the column names in the column list. ) inserts or updates a row of values for the specified columns of a table. INSERT OR UPDATE table ( column, column2. Unless otherwise stated, see INSERT for more details. Special considerations for INSERT OR UPDATE are described on this page. INSERT OR UPDATE uses the same syntax and generally has the same features and restrictions as the INSERT statement. An update occurs even when the specified data values are identical to the existing data.Īn existing row is one in which the value being inserted already exists in a column that contains a unique constraint. If the row being inserted already exists, INSERT OR UPDATE performs an UPDATE operation, updating the row with the specified column values. If the row being inserted does not exist, INSERT OR UPDATE performs an INSERT operation. The INSERT OR UPDATE command is an extension of the INSERT command, with these differences:
