Class GroovyResultSetExtension
java.lang.Object
groovy.lang.GroovyObjectSupport
groovy.sql.GroovyResultSetExtension
- All Implemented Interfaces:
GroovyObject
public class GroovyResultSetExtension extends GroovyObjectSupport
GroovyResultSetExtension implements additional logic for ResultSet. Due to
the version incompatibility between java6 and java5 this methods are moved
here from the original GroovyResultSet class. The methods in this class are
used by the proxy GroovyResultSetProxy, which will try to invoke methods
on this class before invoking it on ResultSet.
This class is not intended to be used directly. Should be used through GroovyResultSetProxy only!

GroovyResultSetExtension
Creates a GroovyResultSet implementation.- Parameters:
set
- the result set
-
-
Method Details
-
getResultSet
Gets the current result set.- Returns:
- the result set
- Throws:
SQLException
- if the result set can not be returned
-
toString
-
invokeMethod
Description copied from interface:GroovyObject
Invokes the given method.- Parameters:
name
- the name of the method to callargs
- the arguments to use for the method call- Returns:
- the result of invoking the method
-
getProperty
Gets the value of the designated column in the current row of as anObject
.- Parameters:
columnName
- the SQL name of the column- Returns:
- the returned column value
- Throws:
MissingPropertyException
- if an SQLException happens while getting the object- See Also:
GroovyObject.getProperty(java.lang.String)
,ResultSet.getObject(java.lang.String)
-
setProperty
Updates the designated column with anObject
value.- Parameters:
columnName
- the SQL name of the columnnewValue
- the updated value- Throws:
MissingPropertyException
- if an SQLException happens while setting the new value- See Also:
GroovyObject.setProperty(java.lang.String, java.lang.Object)
,ResultSet.updateObject(java.lang.String, java.lang.Object)
-
getAt
Supports integer based subscript operators for accessing at numbered columns starting at zero. Negative indices are supported, they will count from the last column backwards.- Parameters:
index
- is the number of the column to look at starting at 1- Returns:
- the returned column value
- Throws:
SQLException
- if something goes wrong- See Also:
ResultSet.getObject(int)
-
putAt
Supports integer based subscript operators for updating the values of numbered columns starting at zero. Negative indices are supported, they will count from the last column backwards.- Parameters:
index
- is the number of the column to look at starting at 1newValue
- the updated value- Throws:
SQLException
- if something goes wrong- See Also:
ResultSet.updateObject(java.lang.String, java.lang.Object)
-
add
Adds a new row to the result set- Parameters:
values
- a map containing the mappings for column names and values- Throws:
SQLException
- if something goes wrong- See Also:
ResultSet.insertRow()
,ResultSet.updateObject(java.lang.String, java.lang.Object)
,ResultSet.moveToInsertRow()
-
normalizeIndex
Takes a zero based index and convert it into an SQL based 1 based index. A negative index will count backwards from the last column.- Parameters:
index
- the raw requested index (may be negative)- Returns:
- a JDBC index
- Throws:
SQLException
- if some exception occurs finding out the column count
-
eachRow
Call the closure once for each row in the result set.- Parameters:
closure
- the closure to perform on each row- Throws:
SQLException
- if something goes wrong
-
next
Moves the cursor down one row from its current position. AgetResultSet()
cursor is initially positioned before the first row; the first call to the methodnext
makes the first row the current row; the second call makes the second row the current row, and so on.If an input stream is open for the current row, a call to the method
next
will implicitly close it. AgetResultSet()
object's warning chain is cleared when a new row is read.- Returns:
true
if the new current row is valid;false
if there are no more rows- Throws:
SQLException
- if a database access error occurs
-
previous
Moves the cursor to the previous row in thisgetResultSet()
object.- Returns:
true
if the cursor is on a valid row;false
if it is off the result set- Throws:
SQLException
- if a database access error occurs or the result set type isTYPE_FORWARD_ONLY

- 1.2
