Ambrose Bierce Many programming techniques use collection types such as arrays, bags, lists, nested tables, sets, and trees.To support these techniques in database applications, PL/SQL provides the datatypes , which allow you to declare index-by tables, nested tables and variable-size arrays.Native Dynamic SQL is an alternative to PL/SQL differs somewhat from other common programming languages, such as C. For example, addresses (also called pointers) are not user-visible in PL/SQL. When the second batch is fetched in the loop, the rows go to positions 0 to 9; and so on. DATE_TABLE; indx NUMBER := 10; BEGIN c := DBMS_SQL. PARSE(c, 'select * from multi_tab order by 1', DBMS_SQL. This enables you to create more general-purpose procedures. DEFINE_ARRAY(c, 4, d_tab2, 5, indx); d := DBMS_SQL. For example, dynamic SQL lets you create a procedure that operates on a table whose name is not known until runtime. This is the first of a series of articles and tips on our findings as we use the software.We have spent a lot of time understanding the conflict detection and resolution capabilities of the software, and wanted to “break it” so we could document how to fix it.
We simply wanted to skip the transaction on each database and continue with replicat processing.
In this chapter, you learn how those types let you reference and manipulate collections of data as whole objects.
You also learn how the datatype is an ordered group of elements, all of the same type.
I thought that when you use the Set Recordset command the recordset is populated with the contents of the target table. Open Recordset("SYS_CONTROL_RECORD") Msg Box rs Ctrl Rec. Path & "\" & "LLSYS.mdb") Set rs Ctrl Rec = db Ctrl Rec.
Fields("mp Sales Rank Tier1") ' Option Explicit Public Sub mod Determine Price() On Error Go To Error Routine Dim db Ctrl Rec As DAO. Open Recordset("SYS_CONTROL_RECORD", db Open Table) Msg Box rs Ctrl Rec.
