DbQuery (Jodd API Documentation)

java.lang.Object
- jodd.db.DbQuery

Direct Known Subclasses:

DbOomQuery
```
public class DbQuery
extends java.lang.Object
```
Encapsulates Statement and all its operations.
It may be:
- used in an un-managed way, created directly from connection;
- managed by DbSession;
- managed by DbThreadSession i.e. ThreadDbSessionHolder.
Query life-cycle states:
- 1) created: statement == null, initialized == false
- 2) initialized: statement != null, initialized == true
- 3) closed: statement == null, initialized == true

Constructor Detail

DbQuery

public DbQuery(java.sql.Connection conn,
       java.lang.String sqlString)

Creates new query.

DbQuery

public DbQuery(DbSession session,
       java.lang.String sqlString)

Creates a new query from DbSession.

DbQuery
```
public DbQuery(java.lang.String sqlString)

Method Detail

preprocessSql

protected java.lang.String preprocessSql(java.lang.String sqlString)

Pre-process SQL before using it.

clearParameters
```
public void clearParameters()
```
Clears the current parameter values immediately.
In general, parameter values remain in force for repeated use of a statement. Setting a parameter value automatically clears its previous value. However, in some cases it is useful to immediately release the resources used by the current parameter values; this can be done by calling the method clearParameters. s

checkCreated
```
protected void checkCreated()
```
Checks if query is created (and not yet initialized or closed) and throws an exception if it is not.

checkInitialized
```
protected void checkInitialized()
```
Checks if query is initialized and throws an exception if it is not.

isClosed
```
public boolean isClosed()
```
Returns true if query is closed.

isActive
```
public boolean isActive()
```
Returns true if query is active: created and possibly initialized. Opened query may be not initialized.

isInitialized
```
public boolean isInitialized()
```
Returns true if query is initialized. Initialized query is the one that has created JDBC statements.

getSession
```
public DbSession getSession()
```
Returns used DbSession.

saveResultSet

protected void saveResultSet(java.sql.ResultSet rs)

Stores result set.

forcePreparedStatement
```
public void forcePreparedStatement()
```
Forces creation of prepared statements.

init
```
public final void init()
```
Initializes the query if not already initialized. Usually, user doesn't have to invoke it at all, since it will be called before all methods that deals directly with JDBC statement. Throws an exception if called on closed query.

initSession
```
protected void initSession(DbSession session)
```
Initializes session. When not specified (i.e. is null), session is fetched from session provider.

initializeJdbc
```
protected void initializeJdbc()
```
Performs JDBC initialization of the query. Obtains connection, parses the SQL query string and creates statements. Initialization is performed only once, when switching to initialized state.

prepareQuery
```
protected void prepareQuery()
```
Prepares the query just after the initialization. Query is fully set and ready.

closeAllResultSets
```
public void closeAllResultSets()
```
Closes all result sets created by this query. Query remains active.

closeQuery
```
protected java.sql.SQLException closeQuery()
```
Closes all assigned result sets and then closes the query. Query becomes closed.

close
```
public void close()
```
Closes the query and all created results sets and detaches itself from the session.

closeResultSet
```
public void closeResultSet(java.sql.ResultSet rs)
```
Closes single result set that was created by this query. It is not necessary to close result sets explicitly, since DbQueryBase.close() method closes all created result sets. Query remains active.

getType
```
public int getType()
```

setType
```
public void setType(int type)
```

typeForwardOnly
```
public void typeForwardOnly()
```

typeScrollSensitive
```
public void typeScrollSensitive()
```

typeScrollInsensitive
```
public void typeScrollInsensitive()
```

getConcurrencyType
```
public int getConcurrencyType()
```

setConcurrencyType

public void setConcurrencyType(int concurrencyType)

concurReadOnly
```
public void concurReadOnly()
```

concurUpdatable
```
public void concurUpdatable()
```

getHoldability
```
public int getHoldability()
```

setHoldability

public void setHoldability(int holdability)

holdCursorsOverCommit
```
public void holdCursorsOverCommit()
```

closeCursorsAtCommit
```
public void closeCursorsAtCommit()
```

isInDebugMode
```
public boolean isInDebugMode()
```

setDebug
```
public void setDebug(boolean debug)
```

setDebugMode
```
public void setDebugMode()
```

getGeneratedColumnNames
```
public java.lang.String[] getGeneratedColumnNames()
```
Returns generated column names.

setGeneratedColumns
```
public void setGeneratedColumns(java.lang.String... columns)
```
Specifies columns which values will be generated by database.

setGeneratedKey
```
public void setGeneratedKey()
```
Specifies that database will generate some columns values, usually the single id.

resetGeneratedColumns
```
public void resetGeneratedColumns()
```
Resets creating generated columns.

getFetchSize
```
public int getFetchSize()
```
Returns fetch size.

See Also:
setFetchSize(int)

setFetchSize
```
public void setFetchSize(int rows)
```
Gives the JDBC driver a hint as to the number of rows that should be fetched from the database when more rows are needed. The number of rows specified affects only result sets created using this statement. If the value specified is zero, then the hint is ignored. The default value is zero.

See Also:
Statement.setFetchSize(int)

getMaxRows
```
public int getMaxRows()
```
Returns max rows.

See Also:
setMaxRows(int)

setMaxRows
```
public void setMaxRows(int maxRows)
```
Sets the limit for the maximum number of rows that any ResultSet object can contain to the given number. If the limit is exceeded, the excess rows are silently dropped. Zero means there is no limit.

See Also:
Statement.setMaxRows(int)

getExecutionTime
```
public long getExecutionTime()
```
Returns query execution elapsed time in milliseconds. Returns -1 if query is still not executed.

execute
```
public java.sql.ResultSet execute()
```
Executes the query. If this method is invoked at least once, the query or all created ResultSets must be explicitly closed at the end of query usage. This can be done explicitly by calling DbQueryBase.closeResultSet(ResultSet) оr implicitly, during DbQueryBase.close().

See Also:
Statement.execute(String)

executeUpdate
```
public int executeUpdate()
```
Executes UPDATE, INSERT or DELETE queries. Query is not closed afterwards unless auto close mode is set.

See Also:
Statement.executeUpdate(String)

executeUpdate
```
protected int executeUpdate(boolean closeQuery)
```
Executes UPDATE, INSERT or DELETE queries and optionally closes the query.

See Also:
Statement.executeUpdate(String)

executeCount
```
public long executeCount()
```
Special execute() for 'select count(*)' queries. Query is not closed after the execution unless auto-close mode is set. Doesn't check if query is really a count query, so it would work for any query that has number in the first column of result. If result set returns zero rows (very unlikely), returns -1.

executeCount
```
protected long executeCount(boolean close)
```
Executes count queries and optionally closes query afterwards.

list

public <T> java.util.List<T> list(QueryMapper<T> queryMapper)

Executes the query, iterates result set and map each row.

find

public <T> T find(QueryMapper<T> queryMapper)

Executes the query and maps single result row.

listSet

public <T> java.util.Set<T> listSet(QueryMapper<T> queryMapper)

Executes the query, iterates all rows and maps them.

getGeneratedColumns

public java.sql.ResultSet getGeneratedColumns()

Returns generated columns.

getGeneratedKey
```
public long getGeneratedKey()
```
Returns generated key i.e. first generated column as long.

getQueryString
```
public java.lang.String getQueryString()
```
Returns query SQL string. For prepared statements, returned sql string with quick-and-dirty replaced values.

toString
```
public java.lang.String toString()
```
Overrides:

toString in class java.lang.Object

See Also:
getQueryString()

getTotalOpenResultSetCount
```
public static int getTotalOpenResultSetCount()
```
Returns total number of open result sets.

See Also:
getOpenResultSetCount()

getOpenResultSetCount
```
public int getOpenResultSetCount()
```
Returns number of created result sets that are still not explicitly closed.

See Also:
getTotalOpenResultSetCount()
