Detailed Description

Utility API for a database. Unless otherwise stated functions here are located in RDM DB Engine Library. Linker option:

    -lrdmrdm

Function Documentation

rdm_dbCreateNewPackFile()

RDM_RETCODE rdm_dbCreateNewPackFile ( RDM_DB db )

#include <rdmdbapi.h>

Create a new pack file.

This API forces the database to create a new pack file. All changes will now be written to the new pack. A new pack is typically created when the current pack reaches the max-pack-file-size threshold. This function forces a new pack independent of the size of the current pack.

This function is located in RDM DB Engine Library. Linker option:

    -lrdmrdm

Locking Requirements: None

Return values

sOKAY	Normal, successful return.
eDBNOTOPEN	Database not open.

See also: rdm_dbSetOptions; rdm_dbVacuum; rdm-vacuum

Parameters

[in] db A valid RDM database handle

rdm_dbExport()

RDM_RETCODE rdm_dbExport	(	RDM_DB	db,
		const char *	optString
	)

#include <rdmdbapi.h>

Database export API.

This API exports data from the database to text files or XML files that can then be moved to another computer or used as input into other tools that read the formatted files (for example: rdm_dbImport()).

The optString argument is a semicolon delimited string of options for the rdm_dbExport() processing. The available options are key/value pairs to set the export processing options (e.g.type=xml).

Options are defined using keys or properties. Every key has a name and a value, delimited by an equals sign (=). The key name appears to the left of the equals sign. Key names are not case-sensitive. Unless otherwise noted, values are not case-sensitive.

Key	Value Description
force	Overwrite an existing export output file.
nocolumnlist	Do not include the list of columns in the generated SQL INSERT statement.
noschema	Do not export the schema definition (SQL export only).
notriggers	Do not export the triggers (SQL export only).
output	Name of the export output file.
schemaonly	Export only the schema definition (SQL export only).
table	Name of the specific table for which to export data.
triggersonly	Export only the triggers (SQL export only).
type	Export file type (XML, CSV, SQL, CAT or STAT).
query	Export the data specified by the SQL query.
usesnapshot	Start a snapshot to read the content of the database.

This function is located in RDM Export Library. Linker option:

    -lrdmexport

Locking Requirements: Read locks on the tables being exported.

Return values

sOKAY	Normal, successful return.
{eDBNOTOPEN

Parameters

[in]	db	A valid RDM database handle
[in]	optString	A semicolon delimited string that contains the utility options

rdm_dbImport()

RDM_RETCODE rdm_dbImport	(	RDM_DB	db,
		const char *	optString
	)

#include <rdmdbapi.h>

Database import API.

This API imports data from comma-separated (CSV), XML or SQL formatted text files into an existing database.

The optString argument is a semicolon delimited string of options for the rdm_dbImport() processing. The available options are key/value pairs to set the import processing options, like: filename=importdata.sql

Note: The filename option is the only required option for the optString argument.

Options are defined using keys or properties. Every key has a name and a value, delimited by an equals sign (=). The key name appears to the left of the equals sign. Key names are not case-sensitive. Unless otherwise noted, values are not case-sensitive.

Key	Value Description
commit	Commit per this number of rows.
timeformat	Specify default display format for time.
table	Specify target table for import.
append	Append to an existing database.
dateformat	Specify default display format for date.
force	Overwrite an existing database.
filename	Name of the text file containing import data.

This function is located in RDM Export Library. Linker option:

    -lrdmexport

Locking Requirements: Write locks on the tables being imported.

Return values

sOKAY	Normal, successful return.
eDBNOTOPEN	Database not open.

See also: rdm_dbStartUpdate; rdm_dbExport; rdm_dbEnd

Parameters

[in]	db	A valid RDM database handle
[in]	optString	A semicolon delimited string that contains the utility options

rdm_dbRebuildKey()

RDM_RETCODE rdm_dbRebuildKey	(	RDM_DB	db,
		RDM_KEY_ID	keyId,
		uint32_t	reportFrequency,
		RDM_REBUILD_INDEX_REPORT_FCN *	fcn
	)

#include <rdmdbapi.h>

Rebuild keys for an index.

This function allows an application to rebuild keys for the index specified by keyId.

If reportFrequency is non-zero and fcn is not NULL, rdm_dbRebuildKey() calls the report function pointed to by fcn every reportFrequency rows it has successfully processed.

Locking Requirements: The table the key is on must be write locked.

Return values

sOKAY	Normal, successful return.
eDBNOTOPEN	Database not open.
eREADONLY	Database is read-only and cannot be updated.
eNOSTARTUPDATE	An update operation was attempted when no rdm_dbStartUpdate() is active.
eNOTLOCKED	Attempt to access a table for reading or update without proper locks.
ePRECOMMITTED	A precommitted transaction must be committed or rolled back before further operations on this database are allowed.

See also: rdm_dbStartUpdate; rdm_dbImport; rdm_dbEnd; rdm_dbRebuildKeys

Parameters

[in]	db	A valid RDM database handle
[in]	keyId	The RDM key identifier
[in]	reportFrequency	how often to report status on the rebuild
[in]	fcn	A function used to report status on the rebuild

rdm_dbRebuildKeys()

RDM_RETCODE rdm_dbRebuildKeys	(	RDM_DB	db,
		uint32_t	numKeys,
		const RDM_KEY_ID *	keyId,
		uint32_t	reportFrequency,
		RDM_REBUILD_INDEX_REPORT_FCN *	fcn
	)

#include <rdmdbapi.h>

Rebuild keys for one or more indexes.

This function allows an application to rebuild the indexes specified by keyId.

If reportFrequency is non-zero and fcn is not NULL, rdm_dbRebuildKeys() calls the report function pointed to by fcn every reportFrequency rows it has successfully processed.

Locking Requirements: The table for each key specified must be write locked.

Return values

sOKAY	Normal, successful return.
eDBNOTOPEN	Database not open.
eREADONLY	Database is read-only and cannot be updated.
eNOSTARTUPDATE	An update operation was attempted when no rdm_dbStartUpdate() is active.
eNOTLOCKED	Attempt to access a table for reading or update without proper locks.
ePRECOMMITTED	A precommitted transaction must be committed or rolled back before further operations on this database are allowed.

See also: rdm_dbStartUpdate; rdm_dbImport; rdm_dbEnd; rdm_dbRebuildKey

Parameters

[in]	db	A valid RDM database handle
[in]	numKeys	The number of keys to rebuild
[in]	keyId	The RDM key identifier
[in]	reportFrequency	how often to report status on the rebuild
[in]	fcn	A function used to report status on the rebuild

rdm_dbVacuum()

RDM_RETCODE rdm_dbVacuum	(	RDM_DB	db,
		const char *	optString
	)

#include <rdmdbapi.h>

Database vacuum API.

This API vacuums delete data from the disk-based database pack files.

This function is located in RDM DB Engine Library. Linker option:

    -lrdmrdm

Locking Requirements: None

Return values

sOKAY	Normal, successful return.
eDBNOTOPEN	Database not open.

See also: rdm_dbSetOptions; rdm_dbCreateNewPackFile; rdm-vacuum
