## Detailed Description

is used for parameter setting, commonly implemented in conjunction with PreparedStatements.

Note: The setXXX methods for setting IN parameter values must specify types that are compatible with the defined SQL type of the input parameter. For instance, if the IN parameter has SQL type Integer, then the method com::sun::star::sdbc::XParameters::setInt() should be used.

If arbitrary parameter type conversions are required, the method com::sun::star::sdbc::XParameters::setObject() should be used with a target SQL type.
Example of setting a parameter; `con` is an active connection.

pstmt = con.prepareStatement("UPDATE EMPLOYEES SET SALARY = ? WHERE ID = ?")
pstmt.setDouble(1, 153833.00)
pstmt.setLong(2, 110592)

## Member Function Documentation

## ◆ clearParameters()

void clearParameters | ( |  | ) |
raises | ( | SQLException ) |  |  |

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 clearParameters.

Exceptions

  SQLException | if a database access error occurs.

## ◆ setArray()

void setArray | ( | [in] long | parameterIndex,
|  | [in] XArray | x )
raises | ( | SQLException ) |  |  |

sets an Array parameter.

Parameters

  parameterIndex | the first parameter is 1, the second is 2, ...
  x | the parameter value

Exceptions

  SQLException | if a database access error occurs.

## ◆ setBinaryStream()

void setBinaryStream | ( | [in] long | parameterIndex,
|  | [in] com::sun::star::io::XInputStream | x,
|  | [in] long | length )
raises | ( | SQLException ) |  |  |

sets the designated parameter to the given input stream, which will have the specified number of bytes.

When a very large binary value is input to a LONGVARBINARY or LONGVARCHAR parameter, it may be more practical to send it via an com::sun::star::io::XInputStream . SDBC will read the data from the stream as needed, until it reaches end-of-file.

Parameters

  parameterIndex | the first parameter is 1, the second is 2, ...
  x | the parameter value
  length | the number of bytes in the stream

Exceptions

  SQLException | if a database access error occurs.

## ◆ setBlob()

void setBlob | ( | [in] long | parameterIndex,

The driver converts this to a SQL BIT value when it sends it to the database.

Parameters

raises | ( | SQLException ) |  |  |

sets the designated parameter to the given input stream, which will have the specified number of bytes.

When a very large binary value is input to a LONGVARCHAR parameter, it may be more practical to send it via a com::sun::star::io::XInputStream . SDBC will read the data from the stream as needed, until it reaches end-of-file.

Parameters

## ◆ setObject()

void setObject | ( | [in] long | parameterIndex,
|  | [in] any | x )
raises | ( | SQLException ) |  |  |

sets the value of a parameter using an any.

The given object will be converted to the targetSqlType before being sent to the database. If the object has a custom mapping (is of a class implementing SQLData), the SDBC driver should call its method `writeSQL` to write it to the SQL data stream. If, on the other hand, the object is of a service implementing Ref, Blob, Clob, Struct, or Array, the driver should pass it to the database as a value of the corresponding SQL type.

Note that this method may be used to pass database-specific abstract data types.

Parameters

  parameterIndex | the first parameter is 1, the second is 2, ...
  x | the parameter value

Exceptions

  SQLException | if a database access error occurs.

## ◆ setObjectNull()

void setObjectNull | ( | [in] long | parameterIndex,
|  | [in] long | sqlType,
|  | [in] string | typeName )
raises | ( | SQLException ) |  |  |

sets the designated parameter to SQL NULL.

This version of setNull should be used for user-named types and REF type parameters. Examples of user-named types include: STRUCT, DISTINCT, OBJECT, and named array types.

Note: To be portable, applications must give the SQL type code and the fully-qualified SQL type name when specifying a NULL user-defined or REF parameter. In the case of a user-named type the name is the type name of the parameter itself. For a REF parameter the name is the type name of the referenced type. If a SDBC driver does not need the type code or type name information, it may ignore it.
Although it is intended for user-named and Ref parameters, this method may be used to set a null parameter of any JDBC type. If the parameter does not have a user-named or REF type, the given typeName is ignored.

Parameters

  parameterIndex | the first parameter is 1, the second is 2, ...
  sqlType | the type of the column to set to `NULL`
  typeName | the name of the type

Exceptions

  SQLException | if a database access error occurs.

## ◆ setObjectWithInfo()

void setObjectWithInfo | ( | [in] long | parameterIndex,
|  | [in] any | x,
|  | [in] long | targetSqlType,
|  | [in] long | scale )
raises | ( | SQLException ) |  |  |

set a value from the Datatype ANY for a parameter.

The given object will be converted to the targetSqlType before being sent to the database. If the object has a custom mapping (is of a class implementing SQLData), the SDBC driver should call its method `writeSQL` to write it to the SQL data stream. If, on the other hand, the object is of a service implementing Ref, Blob, Clob, Struct, or Array, the driver should pass it to the database as a value of the corresponding SQL type.

Note that this method may be used to pass database-specific abstract data types.

Parameters

  parameterIndex | the first parameter is 1, the second is 2, ...
  x | the parameter value
  targetSqlType | the SQL type (as defined in com::sun::star::sdbc::DataType ) to be sent to the database. The scale argument may further qualify this type.
  scale | for com::sun::star::sdbc::DataType::DECIMAL or com::sun::star::sdbc::DataType::NUMERIC types, this is the number of digits after the decimal point. For all other types, this value will be ignored.

Exceptions

  SQLException | if a database access error occurs.

## ◆ setRef()

void setRef | ( | [in] long | parameterIndex,
|  | [in] XRef | x )
raises | ( | SQLException ) |  |  |

sets a REF(&lt;structured-type&gt;) parameter.

Parameters

raises | ( | SQLException ) |  |  |

sets the designated parameter to a string value.
