【问题描述】：
我的问题是：使用 xmla 文件和 SSMS 将 2 个或更多表添加到现有数据库的正确语法是什么？我有一个模型部署到 Azure Analysis Services 服务器。所以数据库已经创建好了。我想通过在 SSMS 中运行一个 xmla 脚本来创建或替换表。
当我使用下面的脚本来创建一个表时，它可以完美运行。但我需要的是使用一个 xmla 脚本创建多个表（不仅仅是一个）。
适用于一张表的脚本
以下脚本完美且正确地“创建或替换”数据库中的一个表。
{
"createOrReplace": {
"object": {
"database": "MyDatabase",
"table": "MyTable"
},
"table": {
"name": "MyTable",
"columns": [
{
"name": "MyTableId",
"dataType": "int64",
"sourceColumn": "MyTableId"
},
{
"name": "MyTable",
"dataType": "string",
"sourceColumn": "MyTable"
}
],
"partitions": [
{
"name": "Partition",
"dataView": "full",
"source": {
"type": "m",
"expression": [
"let",
" Source=GetFileList(),",
" #\"MyTable txt\" = Source{[Name=\"MyTable.txt\"]}[Content],",
" #\"Imported CSV\" = Csv.Document(#\"MyTable txt\",[Delimiter=\",\", Columns=9, Encoding=1252, QuoteStyle=QuoteStyle.None]),",
" #\"Promoted Headers\" = Table.PromoteHeaders(#\"Imported CSV\", [PromoteAllScalars=true]),",
" #\"Changed Type\" = Table.TransformColumnTypes(#\"Promoted Headers\",{{\"MyTableId\", Int64.Type}, {\"MyTable\", type text}, {\"Description\", type text}}),",
" #\"Removed Columns\" = Table.RemoveColumns(#\"Changed Type\",{\"Description\"})",
"in",
" #\"Removed Columns\""
]
}
}
]
}
}
}
我尝试使用下面的代码添加 2 个表，但出现错误 JSON DDL 请求失败并出现以下错误：无法识别的 JSON 属性：表。检查路径“表格”，第 6 行，位置 16..
{
"createOrReplace": {
"database": {
"name": "MyDatabase",
"tables": [
{"name": "TableA",
"columns": [
{
"name": "TableAId",
"dataType": "int64",
"sourceColumn": "TableAId"
},
{
"name": "TableA",
"dataType": "string",
"sourceColumn": "TableA"
}
],
"partitions": [
{
"name": "Partition",
"dataView": "full",
"source": {
"type": "m",
"expression": [
"let",

" #\"Imported CSV\" = Csv.Document(#\"TableA txt\",[Delimiter=\",\", Columns=9, Encoding=1252, QuoteStyle=QuoteStyle.None]),",
" #\"Promoted Headers\" = Table.PromoteHeaders(#\"Imported CSV\", [PromoteAllScalars=true]),",
" #\"Changed Type\" = Table.TransformColumnTypes(#\"Promoted Headers\",{{\"TableAId\", Int64.Type}, {\"TableA\", type text}, {\"Description\", type text}}),",
" #\"Removed Columns\" = Table.RemoveColumns(#\"Changed Type\",{\"Description\"})",
"in",
" #\"Removed Columns\""
]
}
}
] },
{"name": "TableB",
"columns": [
{
"name": "TableBId",
"dataType": "int64",
"sourceColumn": "TableBId"
},
{
"name": "TableB",
"dataType": "string",
"sourceColumn": "TableB"
}
],
"partitions": [
{
"name": "Partition",
"dataView": "full",
"source": {
"type": "m",
"expression": [
"let",
" Source=GetFileList(),",
" #\"TableB txt\" = Source{[Name=\"TableB.txt\"]}[Content],",
" #\"Imported CSV\" = Csv.Document(#\"TableB txt\",[Delimiter=\",\", Columns=11, Encoding=1252, QuoteStyle=QuoteStyle.None]),",
" #\"Promoted Headers\" = Table.PromoteHeaders(#\"Imported CSV\", [PromoteAllScalars=true]),",
" #\"Changed Type\" = Table.TransformColumnTypes(#\"Promoted Headers\",{{\"TableBId\", Int64.Type}, {\"TableB\", type text}, {\"Description\", type text}}),",
" #\"Removed Columns\" = Table.RemoveColumns(#\"Changed Type\",{\"Description\"})",
"in",
" #\"Removed Columns\""
]
}
}
] }
]
}
}
}
我也尝试了下面的代码，但得到了错误 错误 -1055784777：JSON DDL 请求失败并出现以下错误：无法识别的 JSON 属性：表。检查路径'createOrReplace.tables'，第 6 行，位置 14.. JSON DDL 请求失败并出现以下错误：无法识别的 JSON 属性：表。检查路径'createOrReplace.tables'，第 6 行，位置 14..
