IfxStatement (informix-jdbc 4.10.16.2 API)

java.lang.Object
- com.informix.jdbc.IfxStatement

All Implemented Interfaces:

IfmxStatement, java.lang.AutoCloseable, java.sql.Statement, java.sql.Wrapper

Direct Known Subclasses:

IfxPreparedStatement
```
public class IfxStatement
extends java.lang.Object
implements IfmxStatement
```
A Statement object is used for executing a static SQL statement and obtaining the results produced by it.
Only one ResultSet per Statement can be open at any point in time. Therefore, if the reading of one ResultSet is interleaved with the reading of another, each must have been generated by different Statements.

  - transferWarnings
```
protected void transferWarnings()
                         throws java.sql.SQLException
```
    This method is called to transfer warnings reported on a statement from IfxSqli object to the statement object This is needed as resultset object and statement object share same instance of IfxSqli class. As per JDBC documetation , getWarnings() on a resultset object should only return warnings chain caused by resultset methods. and warnings related with execution of a statement should be chained to a statement object .
    
    Throws:
    
    java.sql.SQLException
  - getWarnings
```
public java.sql.SQLWarning getWarnings()
                                throws java.sql.SQLException
```
    The first warning reported by calls on this Statement is returned. A Statment's execute methods clear its SQLWarning chain. Subsequent Statement warnings will be chained to this SQLWarning.
    The warning chain is automatically cleared each time a statement is (re)executed.
    Note: If you are processing a ResultSet then any warnings associated with ResultSet reads will be chained on the ResultSet object.
    
    Specified by:
    
    getWarnings in interface java.sql.Statement
    
    Returns:
    
    the first SQLWarning or null

    java.sql.SQLException
  - clearWarnings
```
public void clearWarnings()
                   throws java.sql.SQLException

  - setCursorName
```
public void setCursorName(java.lang.String name)
                   throws java.sql.SQLException
```
    setCursorName defines the SQL cursor name that will be used by subsequent Statement execute methods. This name can then be used in SQL positioned update/delete statements to identify the current row in the ResultSet generated by this statement. If the database doesn't support positioned update/delete, this method is a noop.
    Note: By definition, positioned update/delete execution must be done by a different Statement than the one which generated the ResultSet being used for positioning. Also, cursor names must be unique within a Connection.
    
    Specified by:
    
    setCursorName in interface java.sql.Statement
    
    Parameters:
    
    name - the new cursor name.
    
    Throws:
    
    java.sql.SQLException
  - execute
```
public boolean execute(java.lang.String sql)
                throws java.sql.SQLException
```
    Execute a SQL statement that may return multiple results. Under some (uncommon) situations a single SQL statement may return multiple result sets and/or update counts. Normally you can ignore this, unless you're executing a stored procedure that you know may return multiple results, or unless you're dynamically executing an unknown SQL string. The "execute", "getMoreResults", "getResultSet" and "getUpdateCount" methods let you navigate through multiple results. The "execute" method executes a SQL statement and indicates the form of the first result. You can then use getResultSet or getUpdateCount to retrieve the result, and getMoreResults to move to any subsequent result(s). We don't ever return update count for this call. If you want an update count, then use executeUpdate.
    
    Specified by:
    
    execute in interface java.sql.Statement
    
    Parameters:
    
    sql - any SQL statement
    
    Returns:
    
    true if the first result is a ResultSet; false if it is an integer

                   throws java.sql.SQLException
```
    getUpdateCount returns the current result, which should be an integer value. It should only be called once per result.
    The only way to tell for sure that the result is an update count is to first test to see if it is a ResultSet. If it is not a ResultSet it is an update count.
    
    Specified by:
    
    getUpdateCount in interface java.sql.Statement
    
    Returns:
    
    the current result as an update count; -1 if it is a ResultSet or there are no more results.
    
    Throws:
    
    java.sql.SQLException
  - getMoreResults
```
public boolean getMoreResults()
                       throws java.sql.SQLException
```
    getMoreResults moves to a Statement's next result. It returns true if this result is a ResultSet. getMoreResults also implicitly closes any current ResultSet obtained with getResultSet.
    
    Specified by:
    
    getMoreResults in interface java.sql.Statement
    
    Returns:
    
    true if the next result is a ResultSet; false if it is an integer Informix is not support multiple Result, therefore, it is always return false.
