QueryBuilder (DataStax Java Driver for Apache Cassandra

java.lang.Object
- com.datastax.driver.core.querybuilder.QueryBuilder

```
public final class QueryBuilder
extends Object
```
Static methods to build a CQL3 query.
The queries built by this builder will provide a value for the Statement.getRoutingKey() method only when a TableMetadata is provided to the builder. It is thus advised to do so if a TokenAwarePolicy is in use.
The provider builders perform very little validation of the built query. There is thus no guarantee that a built query is valid, and it is definitively possible to create invalid queries.
Note that it could be convenient to use an 'import static' to use the methods of this class.

```
Start building a new UPDATE query.

Parameters:

Returns:

an in-construction UPDATE query (at least a SET and a WHERE clause needs to be provided to complete the query).

batch
```
public static Batch batch(RegularStatement... statements)
```
Built a new BATCH query on the provided statements.
This method will build a logged batch (this is the default in CQL3). To create unlogged batches, use unloggedBatch(com.datastax.driver.core.RegularStatement...). Also note that for convenience, if the provided statements are counter statements, this method will create a COUNTER batch even though COUNTER batches are never logged (so for counters, using this method is effectively equivalent to using unloggedBatch(com.datastax.driver.core.RegularStatement...)).

Parameters:

statements - the statements to batch.

Returns:

a new RegularStatement that batch statements.

unloggedBatch
```
public static Batch unloggedBatch(RegularStatement... statements)
```
Built a new UNLOGGED BATCH query on the provided statements.
Compared to logged batches (the default), unlogged batch don't use the distributed batch log server side and as such are not guaranteed to be atomic. In other words, if an unlogged batch timeout, some of the batched statements may have been persisted while some have not. Unlogged batch will however be slightly faster than logged batch.
If the statements added to the batch are counter statements, the resulting batch will be a COUNTER one.

Parameters:

statements - the statements to batch.

Returns:

a new RegularStatement that batch statements without using the batch log.

name - the column name (must be of type set).

set - a bind marker representing the set of values to append

Returns:

the correspond assignment (to use in an update query)

remove
```
public static Assignment remove(String name,
                                Object value)
```
Remove a value from a set column.
This will generate: name = name - {value}.

Parameters:

name - the column name (must be of type set).

value - the value to remove. Using a BindMarker here is not supported. To use a BindMarker use QueryBuilder#removeAll with a singleton set.

Returns:

the correspond assignment (to use in an update query)

```
public static Assignment removeAll(String name,
                                   Set<?> set)
```
Remove a set of values from a set column.
This will generate: name = name - set.

Parameters:

name - the column name (must be of type set).

set - the set of values to remove

Returns:

the correspond assignment (to use in an update query)

removeAll
```
public static Assignment removeAll(String name,
                                   BindMarker set)
```
Remove a set of values from a set column.
This will generate: name = name - set.

Parameters:

name - the column name (must be of type set).

set - a bind marker representing the set of values to remove

Returns:

the correspond assignment (to use in an update query)

put
```
public static Assignment put(String name,
                             Object key,
                             Object value)
```
Puts a new key/value pair to a map column.
This will generate: name[key] = value.

Parameters:

name - the column name (must be of type map).

key - the key to put

value - the value to put

Returns:

the correspond assignment (to use in an update query)

putAll
```
public static Assignment putAll(String name,
                                Map<?,?> map)
```
Puts a map of new key/value pairs to a map column.
This will generate: name = name + map.

Parameters:

name - the column name (must be of type map).

map - the map of key/value pairs to put

Returns:

the correspond assignment (to use in an update query)

putAll
```
public static Assignment putAll(String name,
                                BindMarker map)
```
Puts a map of new key/value pairs to a map column.
This will generate: name = name + map.

Parameters:

name - the column name (must be of type map).

map - a bind marker representing the map of key/value pairs to put

Returns:

the correspond assignment (to use in an update query)

bindMarker

public static BindMarker bindMarker()

An object representing an anonymous bind marker (a question mark).

This can be used wherever a value is expected. For instance, one can do:

 
     Insert i = QueryBuilder.insertInto("test").value("k", 0)
                                               .value("c", QueryBuilder.bindMarker());
     PreparedState p = session.prepare(i.toString());

Returns:: a new bind marker.

bindMarker
```
public static BindMarker bindMarker(String name)
```
An object representing a named bind marker.
This can be used wherever a value is expected. For instance, one can do:
```
 
     Insert i = QueryBuilder.insertInto("test").value("k", 0)
                                               .value("c", QueryBuilder.bindMarker("c_val"));
     PreparedState p = session.prepare(i.toString());
 
 
```
Please note that named bind makers are only supported starting with Cassandra 2.0.1.
Parameters:

name - the name for the bind marker.

Returns:

an object representing a bind marker named name.

raw

public static Object raw(String str)

Protects a value from any interpretation by the query builder.

The following table exemplify the behavior of this function:

Examples of use
Code	Resulting query string
`select().from("t").where(eq("c", "C'est la vie!"));`	`"SELECT * FROM t WHERE c='C''est la vie!';"`
`select().from("t").where(eq("c", raw("C'est la vie!")));`	`"SELECT * FROM t WHERE c=C'est la vie!;"`
`select().from("t").where(eq("c", raw("'C'est la vie!'")));`	`"SELECT * FROM t WHERE c='C'est la vie!';"`
`select().from("t").where(eq("c", "now()"));`	`"SELECT * FROM t WHERE c='now()';"`
`select().from("t").where(eq("c", raw("now()")));`	`"SELECT * FROM t WHERE c=now();"`

Note: the 2nd and 3rd examples in this table are not a valid CQL3 queries.

The use of that method is generally discouraged since it lead to security risks. However, if you know what you are doing, it allows to escape the interpretations done by the QueryBuilder.

Parameters:: str - the raw value to use as a string
Returns:: the value but protected from being interpreted/escaped by the query builder.

fcall
```
public static Object fcall(String name,
                           Object... parameters)
```
Creates a function call.

Parameters:

name - the name of the function to call.

parameters - the parameters for the function.

Returns:

the function call.

now
```
public static Object now()
```
Creates a now() function call.

Returns:

the function call.

uuid
```
public static Object uuid()
```
Creates a uuid() function call.

Returns:

the function call.

column
```
public static Object column(String name)
```
Declares that the name in argument should be treated as a column name.
This mainly meant for use with Select.Selection.fcall(java.lang.String, java.lang.Object...) when a function should apply to a column name, not a string value.

Parameters:

name - the name of the column.

Returns:

the name as a column name.
