Direct Known Subclasses:

JavaConditionStatement.Resolver

public class JavaFieldResolver

extends JavaScriptInvisibleNode

field resolver for sql expression copies.

While writing the PlSql script we might create a cursor that contains some "fields" on return of the select clause. These fields shall be resolved in any of the sql expressions about to be copied directly into the output script - essentially we have to subsitute a "fieldname" by "cursorrecord.fieldname" and we have to ensure that during DynamicSQL we interrupt the string mode.

A necessary prerequisite is simply having a list of mappings of fieldnames into a target clause. We'll also push a set of helper functions into this class that are used anywhere there will be a mapping to be performed.

Method Detail

addAllFromCursorRecord

public void addAllFromCursorRecord(JavaRecordVariable var)

add mapping list from record layout. For each field registered in the given record variable do record a fetch value mapping

add mapping for record prefix. If a given field name exists then assert to fetch it in the script from the given record variable.

replaceSqlTableReferenceNodes

public void replaceSqlTableReferenceNodes(SimpleNode tree)

resolve TableReferences in sql snippets. Scan for SqlTableColumn nodes - fetch its sql name - check whether a name mapping has been registered for that name - replace with a name-node that gets the value from a java sql record variable during JavaScriptInvisibleNode.print(JavaPrintStream)
