# SPI\_prepare\_params

### SPI\_prepare\_params

SPI\_prepare\_params — 準備陳述式，但尚不執行

### 語法

```

SPIPlanPtr SPI_prepare_params(const char * command,
                              ParserSetupHook parserSetup,
                              void * parserSetupArg,
                              int cursorOptions)
```

### 說明

`SPI_prepare_params` 為指定命令建立並回傳已準備的陳述式，但不執行該命令。此函式等同於 `SPI_prepare_cursor`，但呼叫端還可指定剖析器掛鉤函式，以控制外部參數參照的剖析。

此函式現已棄用，請改用 `SPI_prepare_extended`。

### 引數

`const char * command` : 命令字串

`ParserSetupHook parserSetup` : 剖析器掛鉤設定函式

`void * parserSetupArg` : 傳遞給 *`parserSetup`* 的引數

`int cursorOptions` : 游標選項的整數位元遮罩；零代表預設行為

### 回傳值

`SPI_prepare_params` 使用與 `SPI_prepare` 相同的回傳慣例。

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.postgresql.tw/server-programming/spi/spi-interface/spi-spi-prepare-params.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
