jdk.sql.ParameterMetaData — clojure-interop/java.sql 1.0.5

An object that can be used to get information about the types and properties for each parameter marker in a PreparedStatement object. For some queries and driver implementations, the data that would be returned by a ParameterMetaData object may not be available until the PreparedStatement has been executed.

Some driver implementations may not be able to provide information about the types and properties for each parameter marker in a CallableStatement object.

get-parameter-class-name clj

(get-parameter-class-name this param)

Retrieves the fully-qualified name of the Java class whose instances should be passed to the method PreparedStatement.setObject.

param - the first parameter is 1, the second is 2, ... - int

returns: the fully-qualified name of the class in the Java programming language that would be used by the method PreparedStatement.setObject to set the value in the specified parameter. This is the class name used for custom mapping. - java.lang.String

throws: java.sql.SQLException - if a database access error occurs

get-parameter-count clj

(get-parameter-count this)

Retrieves the number of parameters in the PreparedStatement object for which this ParameterMetaData object contains information.

returns: the number of parameters - int

throws: java.sql.SQLException - if a database access error occurs

get-parameter-mode clj

(get-parameter-mode this param)

Retrieves the designated parameter's mode.

param - the first parameter is 1, the second is 2, ... - int

returns: mode of the parameter; one of ParameterMetaData.parameterModeIn, ParameterMetaData.parameterModeOut, or ParameterMetaData.parameterModeInOut ParameterMetaData.parameterModeUnknown. - int

throws: java.sql.SQLException - if a database access error occurs

get-parameter-type clj

(get-parameter-type this param)

Retrieves the designated parameter's SQL type.

param - the first parameter is 1, the second is 2, ... - int

returns: SQL type from java.sql.Types - int

throws: java.sql.SQLException - if a database access error occurs

get-parameter-type-name clj

(get-parameter-type-name this param)

Retrieves the designated parameter's database-specific type name.

param - the first parameter is 1, the second is 2, ... - int

returns: type the name used by the database. If the parameter type is a user-defined type, then a fully-qualified type name is returned. - java.lang.String

throws: java.sql.SQLException - if a database access error occurs

get-precision clj

(get-precision this param)

Retrieves the designated parameter's specified column size.

The returned value represents the maximum column size for the given parameter. For numeric data, this is the maximum precision. For character data, this is the length in characters. For datetime datatypes, this is the length in characters of the String representation (assuming the maximum allowed precision of the fractional seconds component). For binary data, this is the length in bytes. For the ROWID datatype, this is the length in bytes. 0 is returned for data types where the column size is not applicable.

param - the first parameter is 1, the second is 2, ... - int

returns: precision - int

throws: java.sql.SQLException - if a database access error occurs

get-scale clj

(get-scale this param)

Retrieves the designated parameter's number of digits to right of the decimal point. 0 is returned for data types where the scale is not applicable.

param - the first parameter is 1, the second is 2, ... - int

returns: scale - int

throws: java.sql.SQLException - if a database access error occurs

is-nullable clj

(is-nullable this param)

Retrieves whether null values are allowed in the designated parameter.

param - the first parameter is 1, the second is 2, ... - int

returns: the nullability status of the given parameter; one of ParameterMetaData.parameterNoNulls, ParameterMetaData.parameterNullable, or ParameterMetaData.parameterNullableUnknown - int

throws: java.sql.SQLException - if a database access error occurs

signed? clj

(signed? this param)

Retrieves whether values for the designated parameter can be signed numbers.

param - the first parameter is 1, the second is 2, ... - int

returns: true if so; false otherwise - boolean

throws: java.sql.SQLException - if a database access error occurs
