## Details

### E_BOOK_SDB_ERROR

    #define E_BOOK_SDB_ERROR (e_book_backend_sqlitedb_error_quark ())

### Warning

`E_BOOK_SDB_ERROR` has been deprecated since version 3.12 and should not be used in newly-written code. Use EBookSqlite instead

Error domain for EBookBackendSqliteDB operations.

Since 3.8

### enum EBookSDBError

    typedef enum {
    	E_BOOK_SDB_ERROR_CONSTRAINT,
    	E_BOOK_SDB_ERROR_CONTACT_NOT_FOUND,
    	E_BOOK_SDB_ERROR_OTHER,
    	E_BOOK_SDB_ERROR_NOT_SUPPORTED,
    	E_BOOK_SDB_ERROR_INVALID_QUERY,
    	E_BOOK_SDB_ERROR_END_OF_LIST
    } EBookSDBError;

### Warning

`EBookSDBError` has been deprecated since version 3.12 and should not be used in newly-written code. Use EBookSqlite instead

Defines the types of possible errors reported by the EBookBackendSqliteDB

`E_BOOK_SDB_ERROR_CONSTRAINT` | The error occurred due to an explicit constraint
`E_BOOK_SDB_ERROR_CONTACT_NOT_FOUND` | A contact was not found by UID (this is different from a query that returns no results, which is not an error).
`E_BOOK_SDB_ERROR_OTHER` | Another error occurred
`E_BOOK_SDB_ERROR_NOT_SUPPORTED` | A query was not supported
`E_BOOK_SDB_ERROR_INVALID_QUERY` | A query was invalid. This can happen if the sexp could not be parsed or if a phone number query contained non-phonenumber input.
`E_BOOK_SDB_ERROR_END_OF_LIST` | An attempt was made to fetch results past the end of a contact list

### struct EBookBackendSqliteDB

    struct EBookBackendSqliteDB {
    };

### Warning

`EBookBackendSqliteDB` has been deprecated since version 3.12 and should not be used in newly-written code. Use EBookSqlite instead

Contains only private data that should be read and manipulated using the functions below.

Since 3.2

### struct EBookBackendSqliteDBClass

    struct EBookBackendSqliteDBClass {
    };

### Warning

`EBookBackendSqliteDBClass` has been deprecated since version 3.12 and should not be used in newly-written code. Use EBookSqlite instead

Class structure for the EBookBackendSqlite class.

### EbSdbSearchData

    typedef struct {
    	gchar *vcard;
    	gchar *uid;
    	gchar *bdata;
    } EbSdbSearchData;

### Warning

`EbSdbSearchData` has been deprecated since version 3.12 and should not be used in newly-written code. Use EBookSqlite instead

This structure is used to represent contacts returned by the EBookBackendSqliteDB from various functions such as `e_book_backend_sqlitedb_search()`.

The `bdata` parameter will contain any data previously set for the given contact with `e_book_backend_sqlitedb_set_contact_bdata()`.

These should be freed with `e_book_backend_sqlitedb_search_data_free()`.

gchar *`vcard`; | The the vcard string
gchar *`uid`; | The `E_CONTACT_UID` field of this contact
gchar *`bdata`; | Extra data set for this contact.

Since 3.2

### enum EbSdbCursorOrigin

    typedef enum {
    	EBSDB_CURSOR_ORIGIN_CURRENT = 0,
    	EBSDB_CURSOR_ORIGIN_BEGIN,
    	EBSDB_CURSOR_ORIGIN_END
    } EbSdbCursorOrigin;

### Warning

`EbSdbCursorOrigin` has been deprecated since version 3.12 and should not be used in newly-written code. Use EBookSqlite instead

Specifies the start position to in the list of traversed contacts in calls to `e_book_backend_sqlitedb_cursor_step()`.

When an EbSdbCuror is created, the current position implied by `EBSDB_CURSOR_ORIGIN_CURRENT` is the same as `EBSDB_CURSOR_ORIGIN_BEGIN`.

`EBSDB_CURSOR_ORIGIN_CURRENT` | The current cursor position
`EBSDB_CURSOR_ORIGIN_BEGIN` | The beginning of the cursor results.
`EBSDB_CURSOR_ORIGIN_END` | The ending of the cursor results.

Since 3.12

### enum EbSdbCursorStepFlags

    typedef enum {
    	EBSDB_CURSOR_STEP_MOVE = (1 << 0),
    	EBSDB_CURSOR_STEP_FETCH = (1 << 1)
    } EbSdbCursorStepFlags;

### Warning

`EbSdbCursorStepFlags` has been deprecated since version 3.12 and should not be used in newly-written code. Use EBookSqlite instead

Defines the behaviour of `e_book_backend_sqlitedb_cursor_step()`.

`EBSDB_CURSOR_STEP_MOVE` | The cursor position should be modified while stepping
`EBSDB_CURSOR_STEP_FETCH` | Traversed contacts should be listed and returned while stepping.

Since 3.12

### e_book_backend_sqlitedb_error_quark ()

`emailid` : | email id of the user
`folderid` : | folder id of the address-book
`folder_name` : | name of the address-book
`store_vcard` : | True if the vcard should be stored inside db, if FALSE only the summary fields would be stored inside db.
`error` : | A location to store any error that may have occurred. [allow-none]

Like `e_book_backend_sqlitedb_new()`, but allows configuration of which contact fields will be stored for quick reference in the summary. The configuration indicated by `setup` will only be taken into account when initially creating the underlying table, further configurations will be ignored.

The fields `E_CONTACT_UID` and `E_CONTACT_REV` are not optional, they will be stored in the summary regardless of this function's parameters

### Note

Only EContactFields with the type G_TYPE_STRING, G_TYPE_BOOLEAN or E_TYPE_CONTACT_ATTR_LIST are currently supported.

`path` : | location where the db would be created
`emailid` : | email id of the user
`folderid` : | folder id of the address-book
`folder_name` : | name of the address-book
`store_vcard` : | True if the vcard should be stored inside db, if FALSE only the summary fields would be stored inside db.
`setup` : | an ESourceBackendSummarySetup describing how the summary should be setup
`error` : | A location to store any error that may have occurred. [allow-none]
Returns : | The newly created EBookBackendSqliteDB. [transfer full]

Steps `cursor` through it's sorted query by a maximum of `count` contacts starting from `origin`.

If `count` is negative, then the cursor will move through the list in reverse.

If `cursor` reaches the beginning or end of the query results, then the returned list might not contain the amount of desired contacts, or might return no results if the cursor currently points to the last contact. Reaching the end of the list is not considered an error condition. Attempts to step beyond the end of the list after having reached the end of the list will however trigger an `E_BOOK_SDB_ERROR_END_OF_LIST` error.

If `EBSDB_CURSOR_STEP_FETCH` is specified in `flags`, a pointer to a `NULL` GSList pointer should be provided for the `results` parameter.

The result list will be stored to `results` and should be freed with `g_slist_free()` and all elements freed with `e_book_backend_sqlitedb_search_data_free()`.

`cursor` : | The EbSdbCursor to use
`flags` : | The EbSdbCursorStepFlags for this step
`origin` : | The EbSdbCursorOrigin from whence to step
`count` : | A positive or negative amount of contacts to try and fetch
`results` : | A return location to store the results, or `NULL` if `EBSDB_CURSOR_STEP_FETCH` is not specified in `flags`. [out][allow-none][element-type EbSdbSearchData][transfer full]
`error` : | A location to store any error that may have occurred. [allow-none]
Returns : | The number of contacts traversed if successful, otherwise -1 is returned and `error` is set.

Sets the `cursor` position to an Alphabetic Index into the alphabet active in `ebsdb`'s locale.

After setting the target to an alphabetic index, for example the index for letter 'E', then further calls to `e_book_backend_sqlitedb_cursor_step()` will return results starting with the letter 'E' (or results starting with the last result in 'D', if moving in a negative direction).

The passed index must be a valid index in the active locale, knowledge on the currently active alphabet index must be obtained using ECollator APIs.

Use `e_book_backend_sqlitedb_ref_collator()` to obtain the active collator for `ebsdb`.
