![]() Performs a query to retrieve the present value of the COUNT column whenever an update is encountered. Raises an exception for the specified error. Table 7-6 Using Multiple FILTER Statements Parameter file This option is useful when you need to trigger an event in response to the failure. ![]() Use the RAISEERROR option of FILTER in the MAP parameter to generate a user-defined error when the filter fails. ON INSERT | ON UPDATE | ON DELETE IGNORE INSERT | IGNORE UPDATE | IGNORE DELETE Use the following FILTER options to specify which SQL operations a filter clause affects. Parentheses (for grouping results in the expression) Results derived from comparisons can be zero (indicating FALSE) or non-zero (indicating TRUE). See Testing and Transforming Data for more information about Oracle GoldenGate conversion functions. These functions are built into Oracle GoldenGate so that you can perform tests, manipulate data, retrieve values, and so forth. Valid FILTER clause elements are the following:Īn Oracle GoldenGate column-conversion function. The sytax for FILTER in a MAP statement is as follows and includes an error-handling option. The syntax for FILTER in a TABLE statement is as follows: To view the underlying SQL, click the SQL tab.To filter a column based on a string, use one of the Oracle GoldenGate string functions or use a WHERE clause.Only applicable for columns included in output.ĭeselect the column, excluding it from the query.Īs you select columns and define conditions, Query Builder writes the SQL for you. Specify columns to be used for grouping when an aggregate function is used. VARCHAR2, CHAR columns - COUNT, COUNT DISTINCT, INITCAP, LENGTH, LOWER, LTRIM, RTRIM, TRIM, UPPERĭATE, TIMESTAMP columns - COUNT, COUNT DISTINCT, TO_CHAR YEAR, TO_CHAR QUARTER, TO_CHAR MONTH, TO_CHAR DAY, TO_CHAR DAY OF YEAR, TO_CHAR WEEK NUMBER columns - COUNT, COUNT DISTINCT, AVG, MAX, MIN, SUM Available functions are dependent on the column type and include: In the Design Pane, select ename and deptno.įor the deptno column, in Condition enter =10 and deselect the Show check box. It is not necessary to select Show to add a column to the query for filtering only.įor example, suppose you want to create following query: Select this check box to include the column in your query results. Consider the following examples:Įnter a number (1, 2, 3, and so on) to specify the order in which selected columns should display. ![]() When specifying a column condition, you must include the appropriate operator and operand. The condition you enter modifies the query's WHERE clause. Aliases make a column name more descriptive, shorten the column name, or prevent possible ambiguous references.

The SQL view presents a read-only, formatted representation of the SQL generated by Query Builder. You can create queries and save the query for later use. You can create relationships between objects by creating a join. Use the Object Selection pane to search for and view tables, views, and materialized views within the current schema as well as select objects.Īs you select columns within an object, you can specify conditions on the Conditions tab.
