field

Valid values are -1 for the objectID and -2 for the row count with multi-entry indexes, all others values are the schema array index value of the field. The absolute field positon values for sub-table fields are as follws in the diagram below.

mode

Valid modes for types within CODBPP::B_TREE index types are CODBPP::ASTR and CODBPP::USTR are CODBPP::DESCENDING or CODBPP::INVERTED or (CODBPP::TO_UPPER_CASE xor CODBPP::TO_LOWER_CASE). Valid modes for all types are CODBPP::DESCENDING or CODBPP::NONE. Valid modes for type within CODBPP::S_TREE indexes are CODBPP::NONE only. Valid modes for type within CODBPP::A_LIST and CODBPP::U_LIST indexes are CODBPP::TOKEN_FIELD or (CODBPP::TO_UPPER_CASE xor CODBPP::TO_LOWER_CASE), the binary fields within a token index are by default value.

Remarks

CODBPP database;
CODBPP::Schema schema;
CODBPP::Field fields[3];
memset(&schema,0,sizeof(CODBPP::Schema));
schema.tableName = u"Table Name";
schema.fieldCount = 3;
schema.fields = &fields;
memset(schema.fields,0,schema.fieldCount * sizeof(CODBPP::Field));
schema.fields[0].type = CODBPP::UINT32;
schema.fields[0].name = u"First";
schema.fields[1].type = CODBPP::FLOAT64;
schema.fields[1].name = u"Second";
schema.fields[2].type = CODBPP::ASTR;
schema.fields[2].name = u"Third";
if(database.OpenDatabase(u"YourDatabase") == NO_ERROR){
