Method Details
Returns the SQL code representing the token.
public string __toString ( ) | ||
return | string | SQL code. |
---|
Returns child tokens.
public yii\db\SqlToken[] getChildren ( ) | ||
return | yii\db\SqlToken[] | Child tokens. |
---|
Returns whether the token represents a collection of tokens and has non-zero number of children.
public boolean getHasChildren ( ) | ||
return | boolean | Whether the token has children. |
---|
Returns whether the token represents a collection of tokens.
public boolean getIsCollection ( ) | ||
return | boolean | Whether the token represents a collection of tokens. |
---|
Returns the SQL code representing the token.
public string getSql ( ) | ||
return | string | SQL code. |
---|
Returns whether this token (including its children) matches the specified "pattern" SQL code.
Usage Example:
$patternToken = (new \yii\db\sqlite\SqlTokenizer('SELECT any FROM any'))->tokenize();
if ($sqlToken->matches($patternToken, 0, $firstMatchIndex, $lastMatchIndex)) {
// ...
}
public boolean matches ( yii\db\SqlToken $patternToken, $offset = 0, &$firstMatchIndex = null, &$lastMatchIndex = null ) | ||
$patternToken | yii\db\SqlToken | Tokenized SQL code to match against. In addition to normal SQL, the
|
$offset | integer | Token children offset to start lookup with. |
$firstMatchIndex | integer|null | Token children offset where a successful match begins. |
$lastMatchIndex | integer|null | Token children offset where a successful match ends. |
return | boolean | Whether this token matches the pattern SQL code. |
