public Builder(String sql,
               Database db)

    Parameters:
    
    sql -
    
    db -
- Method Detail
  - parameters
```
public <T> QueryUpdate.Builder parameters(rx.Observable<T> parameters)
```
    Appends the given parameters to the parameter list for the query. If there are more parameters than required for one execution of the query then more than one execution of the query will occur.
    
    Parameters:
    
    parameters -
    
    Returns:
    
    this
  - parameters
```
public QueryUpdate.Builder parameters(Object... objects)
```
    Appends the given parameter values to the parameter list for the query. If there are more parameters than required for one execution of the query then more than one execution of the query will occur.
    
    Parameters:
    
    objects -
    
    Returns:
    
    this
  - parameter
```
public QueryUpdate.Builder parameter(Object value)
```
    Appends a parameter to the parameter list for the query. If there are more parameters than required for one execution of the query then more than one execution of the query will occur.
    
    Parameters:
    
    value -
    
    Returns:
    
    this
  - parameter
```
public QueryUpdate.Builder parameter(String name,
                                     Object value)
```
    Sets a named parameter. If name is null throws a NullPointerException. If value is instance of Observable then throws an IllegalArgumentException.
    
    Parameters:
    
    name - the parameter name. Cannot be null.
    
    value - the parameter value
  - parameterClob
```
public QueryUpdate.Builder parameterClob(String value)
```
    Appends a parameter to the parameter list for the query for a CLOB parameter and handles null appropriately. If there are more parameters than required for one execution of the query then more than one execution of the query will occur.
    
    Parameters:
    
    value - the string to insert in the CLOB column
    
    Returns:
    
    this
  - parameterBlob
```
public QueryUpdate.Builder parameterBlob(byte[] bytes)
```
    Appends a parameter to the parameter list for the query for a CLOB parameter and handles null appropriately. If there are more parameters than required for one execution of the query then more than one execution of the query will occur.
    
    Parameters:
    
    value -
    
    Returns:
    
    this
  - dependsOn
```
public QueryUpdate.Builder dependsOn(rx.Observable<?> dependency)
```
    Appends a dependency to the dependencies that have to complete their emitting before the query is executed.
    
    Parameters:
    
    dependency -
    
    Returns:
    
    this
  - dependsOnLastTransaction
```
public QueryUpdate.Builder dependsOnLastTransaction()
```
    Appends a dependency on the result of the last transaction ( true for commit or false for rollback) to the dependencies that have to complete their emitting before the query is executed.
    
    Returns:
    
    this
  - returnGeneratedKeys
```
public QueryUpdate.ReturnGeneratedKeysBuilder returnGeneratedKeys()
```
    Returns a builder used to specify how to process the generated keys ResultSet. Not all jdbc drivers support this functionality and some have limitations in their support (h2 for instance only returns the last generated key when multiple inserts happen in the one statement).
    
    Returns:
    
    a builder used to specify how to process the generated keys ResultSet
  - count
```
public rx.Observable<Integer> count()
```
    Returns an Observable with the count of rows affected by the update statement.
    
    Returns:
    
    Observable of counts of rows affected.
  - execute
```
public int execute()
```
    Executes the update query immediately, blocking till completion and returns total of counts of records affected.
    
    Returns:
    
    total of counts of records affected by update queries
  - parameterTransformer
```
public rx.Observable.Transformer<Object,Integer> parameterTransformer()
```
    Returns an Observable.Transformer to allow the query to be pushed parameters via the Observable.compose(Transformer) method.
    
    Returns:
    
    Transformer that acts on parameters
  - dependsOnTransformer
```
public rx.Observable.Transformer<Object,Integer> dependsOnTransformer()
```
    Returns an Observable.Transformer to allow the query to be pushed dependencies via the Observable.compose(Transformer) method.
    
    Returns:
    
    Transformer that acts on dependencies
  - parameterListTransformer
```
public rx.Observable.Transformer<rx.Observable<Object>,rx.Observable<Integer>> parameterListTransformer()
```
    Returns an Observable.Transformer to allow the query to be run once per parameter list in the source.
    
    Returns:
    
    transformer
  - clearParameters
```
public QueryUpdate.Builder clearParameters()
```
    Clears the parameter inputs for the query.
    
    Returns:
    
    the current builder
