sqlparser java如何處理視圖和存儲過程

在Java中使用SQLParser庫處理視圖和存儲過程時，首先需要將SQLParser庫添加到項目中。如果你使用的是Maven項目，可以在pom.xml文件中添加以下依賴：

<dependency>
    <groupId>com.github.javaparser</groupId>
    <artifactId>javaparser-symbol-solver-core</artifactId>
    <version>3.23.1</version>
</dependency>

接下來，你可以使用以下代碼示例來處理視圖和存儲過程：

1. 處理視圖：

import com.github.javaparser.StaticJavaParser;
import com.github.javaparser.ast.CompilationUnit;
import com.github.javaparser.ast.ImportDeclaration;
import com.github.javaparser.ast.Node;
import com.github.javaparser.ast.NodeList;
import com.github.javaparser.ast.expr.MethodCallExpr;
import com.github.javaparser.ast.stmt.Statement;

import java.io.File;
import java.io.IOException;
import java.util.List;

public class SQLParserExample {
    public static void main(String[] args) throws IOException {
        File viewFile = new File("path/to/your/view/definition.sql");
        String viewSql = readFileContent(viewFile);

        CompilationUnit compilationUnit = StaticJavaParser.parse(viewSql);
        NodeList<ImportDeclaration> importDeclarations = compilationUnit.getImports();

        for (ImportDeclaration importDeclaration : importDeclarations) {
            if (importDeclaration.getName().toString().equalsIgnoreCase("your_view_name")) {
                NodeList<Statement> statements = compilationUnit.getStatements();
                for (Statement statement : statements) {
                    if (statement instanceof MethodCallExpr) {
                        MethodCallExpr methodCallExpr = (MethodCallExpr) statement;
                        System.out.println("View name: " + methodCallExpr.getName());
                        System.out.println("Parameters: " + methodCallExpr.getArguments());
                    }
                }
            }
        }
    }

    private static String readFileContent(File file) throws IOException {
        StringBuilder content = new StringBuilder();
        try (java.io.BufferedReader reader = new java.io.BufferedReader(new java.io.FileReader(file))) {
            String line;
            while ((line = reader.readLine()) != null) {
                content.append(line).append("\n");
            }
        }
        return content.toString();
    }
}

2. 處理存儲過程：

import com.github.javaparser.StaticJavaParser;
import com.github.javaparser.ast.CompilationUnit;
import com.github.javaparser.ast.ImportDeclaration;
import com.github.javaparser.ast.Node;
import com.github.javaparser.ast.NodeList;
import com.github.javaparser.ast.expr.MethodCallExpr;
import com.github.javaparser.ast.stmt.Statement;

import java.io.File;
import java.io.IOException;
import java.util.List;

public class SQLParserExample {
    public static void main(String[] args) throws IOException {
        File procedureFile = new File("path/to/your/procedure/definition.sql");
        String procedureSql = readFileContent(procedureFile);

        CompilationUnit compilationUnit = StaticJavaParser.parse(procedureSql);
        NodeList<ImportDeclaration> importDeclarations = compilationUnit.getImports();

        for (ImportDeclaration importDeclaration : importDeclarations) {
            if (importDeclaration.getName().toString().equalsIgnoreCase("your_procedure_name")) {
                NodeList<Statement> statements = compilationUnit.getStatements();
                for (Statement statement : statements) {
                    if (statement instanceof MethodCallExpr) {
                        MethodCallExpr methodCallExpr = (MethodCallExpr) statement;
                        System.out.println("Procedure name: " + methodCallExpr.getName());
                        System.out.println("Parameters: " + methodCallExpr.getArguments());
                    }
                }
            }
        }
    }

    private static String readFileContent(File file) throws IOException {
        StringBuilder content = new StringBuilder();
        try (java.io.BufferedReader reader = new java.io.BufferedReader(new java.io.FileReader(file))) {
            String line;
            while ((line = reader.readLine()) != null) {
                content.append(line).append("\n");
            }
        }
        return content.toString();
    }
}

請注意，這些示例代碼僅適用于簡單的視圖和存儲過程定義。實際上，你可能需要根據你的需求對代碼進行調整。
