The syntax to ALIAS A TABLE in Oracle/PLSQL is: table_name alias_name Parameters or Arguments column_name The original name of the column that you wish to alias. At that point, the loop completes. The range is part of an iteration scheme, which is enclosed by the keywords FOR and LOOP. In the following example, it will loop through all the records from EMP table where department is equal … You cannot refer to its fields outside the loop. This process repeats until the value of the index is greater than the value of upper_bound. PL/SQL GOTO statement example. The loop body is executed once for each integer in the range defined by lower_bound..upper_bound. A cursor parameter can appear in a query wherever a constant can appear. See "PLS_INTEGER Datatype". 1 In Oracle there is a similar statement called EXIT that either exits a loop or a function/procedure (if there is no loop to exit from). Using labels with loops. Inside the loop, you can reference index but you cannot change its value. You can exit not only the current loop, but any enclosing loop. You can exit not only the current loop, but any enclosing loop. PL/SQL loop statements 3 different forms: Basic LOOP; WHILE LOOP; FOR LOOP; Oracle recommended to write a label when use loop statement. This is a convenient technique that makes processing a query as simple as reading lines of text in other programming languages. The syntax for the GOTO statement in Oracle/PLSQL consists of two parts - the GOTO statement and the Label Declaration: GOTO statement. An implicitly declared record. <> The Goto statement can traverse both forward and reverse in the code. The Goto statement must be followed by the label name (without the angle braces) and the label name used by the Goto statement must be enclosed by two angle braces as like below. It is evaluated with each iteration of the loop. In the following example, wages is an alias for the select item salary+NVL(commission_pct,0)*1000: By default, iteration proceeds upward from the lower bound to the upper bound. PL/SQL loops can be labeled. Their names were changed to associative arrays in Oracle 9i release 1. Pl sql goto statement: The pl sql goto statement provides an unconditional jump from the GOTO to a labeled statement in the same subprogram. Since no label is mentioned by default it will take the value from an inner block, hence printing 'inner_block' message. The range is part of an iteration scheme, which is enclosed by the keywords FOR and LOOP. Its scope is the loop itself; you cannot reference the index outside the loop. This basic LOOP statement consists of a LOOP keyword, a body of executable code, and the END LOOP keywords. See "SELECT INTO Statement". Fields in the record store column values from the implicitly fetched row. You can add a WHEN to check for some condition. A simple Goto Statement. The magnitude range of a PLS_INTEGER is +/- 2**31. The record has the same structure as a row retrieved by cursor_name or select_statement. Its syntax is like that of select_into_statement without the INTO clause. A loop that executes an unlimited number of times. label_name must be enclosed by double angle brackets and must appear at the beginning of the loop. Labeling a PL/SQL Loop. The implicit declaration of index_name overrides any other declaration outside the loop. The cursor is also closed automatically if an exception is raised inside the loop. If the Boolean expression in the WHEN clause returns TRUE, the loop is exited immediately. The implicit declaration of index_name overrides any other declaration outside the loop. You cannot refer to its fields outside the loop. Because select_statement is not an independent statement, the implicit cursor SQL does not apply to it. LOOP … END LOOP as well as WHILE LOOP … END LOOP, require explicit processing of the cursor with OPEN, FETCH and CLOSE statements . See Example 4-15, "Using a Label for Referencing Variables Outside a Loop". The lower bound need not be 1, it can be a negative integer as in FOR i IN -5..10. Reverse FOR Loop. If the value of the index is still not less than the value of lower_bound, the sequence of statements is executed again. This is a convenient technique that makes processing a query as simple as reading lines of text in other programming languages. If the expression returns TRUE, the sequence of statements is executed, then control resumes at the top of the loop.
