Constructor Detail

TExecImmeStmt

public TExecImmeStmt(EDbVendor dbvendor)

Method Detail

getEvaluatedDynamicSQLs

public ArrayList<String> getEvaluatedDynamicSQLs()

getDynamicStatements

public TStatementList getDynamicStatements()

Returns:

sql statement instance that generated dynamically based on dynamicSQL

getDynamicSQL

public String getDynamicSQL()

Returns:

String representation of dynamic sql statement. if there is a variable in dynamicStringExpr, value of this variable will be returned.

getBindArguments

public TBindArgumentList getBindArguments()

bind arguments

Returns:

bind arguments in using clause.

getDynamicStringExpr

public TExpression getDynamicStringExpr()

String expr

Returns:

A string literal, string variable, or string expression that represents any SQL statement. this is the original string of dynamic sql statement.

getIntoVariables

public TExpressionList getIntoVariables()

Into variable

Returns:

variable names in the into clause.

getReturnNames

public TObjectNameList getReturnNames()

Used if and only if dynamic_sql_stmt has a RETURNING INTO clause, this clause returns the column values of the rows affected by dynamic_sql_stmt, in either individual variables or records

Returns:

doParseStatement

public int doParseStatement(TCustomSqlStatement psql)

Overrides:

doParseStatement in class TBlockSqlStatement

accept

public void accept(TParseTreeVisitor v)

Description copied from class: TParseTreeNode

Accept a visitor

Specified by:

accept in interface Visitable

Overrides:

accept in class TBlockSqlStatement

Parameters:

v - visitor is a descendant class of TParseTreeVisitor

acceptChildren

public void acceptChildren(TParseTreeVisitor v)

Description copied from class: TParseTreeNode

Accept a visitor to iterate this class and sub-nodes of this class

Specified by:

acceptChildren in interface Visitable

Overrides:

acceptChildren in class TBlockSqlStatement

Parameters:

v - visitor is a descendant class of TParseTreeVisitor

setDynamicStringExpr

public void setDynamicStringExpr(TExpression dynamicStringExpr)

setBindArguments

public void setBindArguments(TBindArgumentList bindArguments)

setIntoVariables

public void setIntoVariables(TExpressionList intoVariables)

setReturnNames

public void setReturnNames(TObjectNameList returnNames)

setDynamicSQL

public void setDynamicSQL(String dynamicSQL)

isDynamicSQLPartial

public boolean isDynamicSQLPartial()

True when getDynamicSQL() was only partially resolved: it contains placeholder identifiers for unknowable parts (unresolved variables, function calls) alongside resolved literal text. Such text is still worth analyzing for approximate lineage, but a parse failure on it must not be reported as a syntax error.

setDynamicStatements

public void setDynamicStatements(TStatementList dynamicStatements)
