This operation creates an entity instance in an edmModel in a remote EDMdatabase and in the same operation, optionally puts values into any number of its attributes.
This operation is only applicable on data models.

Arguments


TypeNameComment
SdaiServerContext 

serverContextId

Context identification, from edmiDefineServerContext

SdaiModel         

remoteModelId

The numeric modelID that uniquely identifies the edmModel in the remote EDMdatabase in which the instance is to be created.

SdaiEntity        

entityId

The numeric entityID that uniquely identifies the entity definition instance in the dictionary model within the remote EDMdatabase. The entityID is returned by the edmiRemoteGetEntity function.

SdaiInteger       

attributes

The number of attribute values given in the variable argument list <values>.

SdaiAppInstance   

newInstanceId

Variable that will receive the numeric instanceID that uniquely identifies the created instance in the remote EDMdatabase.

SdaiInvocationId  

edmiInvocationId

Currently not used.

SdaiAttr 

values

A numeric attributeID that uniquely identifies an attribute definition instance in the remote EDMdatabase. The attributeIDs are returned from the edmiRemoteGetAttrDefinition and edmiRemoteGetAttrDefinitionBN functions.

SdaiPrimitiveType 
 The specified primitive type must be the same or a compatible data type of the actual attribute domain as defined in the attribute declaration in the related EXPRESS schema. All data types except sdaiAGGR can be handled by this operation. Aggregates cannot be assigned as attribute data value by this operation. Aggregates must be assigned to attributes by either edmiRemoteCreateAggrAndWriteAggrElements or edmiRemoteCreateAggrAndWriteAggrElementsBN operations. The primitive type sdaiSELECT can be used to write any data type. The primitive type sdaiADB can be used to write any data type except typed values.  The primitive type sdaiINTEGER is compatible with sdaiREAL, and sdaiBOOLEAN is compatible with sdaiLOGICAL, hence automatic conversion between these compatible data types will be performed when required.  The data type sdaiAGGR is illegal in this operation.
SdaiVoid 
 The data value to assign to the attribute in the created instance. The type of <value>must be the same as that specified in the <valueType> argument.

 

Return Value


Error rendering macro 'excerpt-include' : User 'null' does not have permission to view the page 'US:_r_EDMInterface'.

This operation creates an entity instance in an edmModel in a remote EDMdatabase and in the same operation, optionally puts values into any number of its attributes.
This operation is only applicable on data models.

                                                 SdaiString        remoteRepositoryName,

                                                 ...); 
 
Arguments:

serverContextId

Context identification, from edmiDefineServerContext

remoteRepositoryName

The name of the edmRepository in the remote  EDMdatabase  that contains the edmModel in which to create an instance. Repository names are case sensitive.

remoteModelName

The name of the edmModel in which to create an instance. Model names are case sensitive.

entityName

Name of the entity that defines the instance type to create. Entity names are case insensitive. The entity must be defined in the underlying schema of the edmModel specified by the <remoteModelName> argument.

attributes

The number of attribute values given in the variable argument list <values>.

newInstanceId

Variable that will receive the numeric instanceID that uniquely identifies the created instance in the remote  EDMdatabase

edmiInvocationId

Currently not used.

values

For each attribute value to assign, the three following arguments in the following order must be specified:

  1. < attributeName >: The name of the attribute to assign a value. Attribute names are case insensitive. The attribute name must be qualified with the entity name when the attribute name is not unique.
  2. <valueType> : The specified primitive type must be the same or a compatible data type of the actual attribute domain as defined in the attribute declaration in the related EXPRESS schema.

    All data types except sdaiAGGR can be handled by this operation. Aggregates cannot be assigned as attribute data value by this operation. Aggregates must be assigned to attributes by either edmiRemoteCreateAggrAndWriteAggrElements or edmiRemoteCreateAggrAndWriteAggrElementsBN operations. The primitive type sdaiSELECT can be used to write any data type. The primitive type sdaiADB can be used to write any data type except typed values.
    The primitive type sdaiINTEGER is compatible with sdaiREAL, and sdaiBOOLEAN is compatible with sdaiLOGICAL, hence automatic conversion between these compatible data types will be performed when required.
    The data type sdaiAGGR is illegal in this operation.
    3. <value>: The data value to assign to the attribute in the created instance. The type of <value>must be the same as that specified in the <valueType> argument.

Returns:
A completion code of datatype EdmiError is the returned function value. The completion code has the following values:
Completion code = 0 : Operation successfully performed.
Completion code != 0: Error in operation. Completion code is an  EDMinterface  error code. Use edmiGetErrorText to get the error text corresponding to the error code.
Example:
EdmiError rstat;
SdaiServerContext myContext;
SdaiInstance instId;
 
/* Create Server Context */
rstat = edmiDefineServerContext("MyContext",
"Johnny", "Supervisor", "cf37ftr", 
"TCP", "9090", "MyServerHost", 
NULL, NULL, NULL, NULL, NULL, &myContext); 
 
rstat = edmiRemoteCreateInstanceAndPutAttrsBN(myContext,
"DataRepository", "MySocialNetwork",  
"PERSON", 4, &instId, NULL, 
"NAME", sdaiSTRING, "Lucy Schmidt", 
"AGE", sdaiINTEGER, 32, 
"WEIGHT", sdaiREAL, 59.5, 
"MARRIED", sdaiBOOLEAN, sdaiFALSE);
