eu.cqse.check.abap.OpenSqlWriteStatement

public abstract class OpenSqlWriteStatement
extends java.lang.Object

Representation of a SQL-like ABAP statement that modifies database table's contents. This offers more detailed analysis, e.g. finding out whether the targeted table is in the standard namespace.

Field Detail

tokens

protected java.util.List<IToken> tokens

The tokens that constitute the statement.

entity

protected ShallowEntity entity

An entity representing an OpenSQL statement directly or an entity representing a macro which contains an OpenSQL statement.

typeResolution

protected ITypeResolution typeResolution

Type resolution of OpenSQL statement.

Method Detail

getTableTokenIndex

protected int getTableTokenIndex()

Determines the token index at which the table name starts. Returns 1 by default.

hasSureITabSyntax

protected abstract boolean hasSureITabSyntax()

Checks whether the statement is targeted at an internal table. Returns true if it is sure from the statement syntax alone that an iTab is targeted.

targetsInternalTable

public boolean targetsInternalTable()

Checks whether the target table of the statement is a variable.

getStatementStartToken

public IToken getStatementStartToken()

Gets the statement start token, e.g. INSERT.

getTableName

public java.lang.String getTableName()

Returns the name of the targeted table in upper case.

getTableNameToken

public IToken getTableNameToken()

Returns the IToken holding the table name

targetsStandardDatabaseTable

public boolean targetsStandardDatabaseTable()

Checks whether the statement targets a standard database table, i.e. a database table from an SAP namespace. Uses the ITypeResolution to distinguish local variables from standard tables.

create

public static OpenSqlWriteStatement create(ShallowEntity entity,
                                           java.util.List<IToken> tokens,
                                           ITypeResolution typeResolution)

Factory method. tokens must be one of INSERT, MODIFY, UPDATE, DELETE. Returns null if passed token list is not an OpenSQL statement targeting a database table.

Throws:

java.lang.IllegalArgumentException - In case the statement has an unsupported type.
